Haiti floods kill four as homes are inundated in the Grand Sud

UN OCHA's Flash Update No. 1, dated 28 October 2026, reports flooding after heavy rains in Haiti's Grand Sud. Four people had died: three in Nippes and one in the South-East. Two fishermen were missing in Abricots, Grand'Anse. These are figures in OCHA's dated update, not a comprehensive later assessment. In Nippes, 1,920 families were affected; 1,767 houses were flooded and 48 small houses destroyed. OCHA also reported 630 flooded houses in Grand'Anse, four houses washed away in Gommiers, and 200 flooded houses in Les Cayes. Corail hospital was flooded. Haiti's Directorate General of Civil Protection (DGPC) had issued an orange alert for heavy rain. The alert is reported as part of the dated situation update. The update does not provide a consolidated estimate of displaced people. Figures describe the locations and snapshot identified by OCHA and should not be added together as a single affected-population total.

DR Congo Ebola outbreak reaches 10,141 confirmed cases

The Bundibugyo virus disease outbreak in the Democratic Republic of the Congo reached 10,141 confirmed cases as of 26 October 2026, according to the World Health Organization (WHO). The total included 4,928 confirmed deaths and 2,708 recoveries. This is an increase of 177 confirmed cases, 87 confirmed deaths and 38 recoveries from WHO's 24 October DRC snapshot. WHO notes that government figures are updated from the previous day's situation report and may be retrospectively revised. The latest detailed WHO outbreak notice reported expansion to 66 health zones across eight provinces as of 20 October. Nord-Ubangi was the most recently affected province, reporting three confirmed cases including one death, while Dakwa in Haut-Uélé was the most recently affected health zone. Fifty of the 66 affected zones reported at least one new case during the preceding 21 days. Ituri remained the most extensively affected province, followed by North Kivu. Conflict, insecurity, displacement and limited access to services continue to complicate surveillance, contact tracing, infection prevention and timely care. WHO separately reports nine cases including two deaths in Kenya and one confirmed case in Nigeria, all with data as of 26 October. These country series remain separately scoped and are not added to the DR Congo story total. A current, attributable same-outbreak WHO image from Bunia is retained with source credit; it illustrates response operations and does not claim to depict the 26 October case update itself.

Yemen displacement reaches 276,301 as IOM tracks escalation

As of 24 October 2026, IOM Yemen’s Displacement Tracking Matrix (DTM) recorded 276,301 internally displaced people (46,044 households) cumulatively since the escalation began in June. Of that total, 275,245 people (45,868 households) were displaced between 1 August and 24 October. These overlapping source-defined scopes are not added together. IOM previously reported that more than 184,000 people were displaced between 1 August and 4 October 2026 as fighting intensified in Yemen. Its Displacement Tracking Matrix recorded 21,798 people, or 3,633 households, displaced at least once between 27 September and 3 October, a 26 per cent increase on the previous week, followed by another 6,474 people, or 1,079 households, displaced on 4 October alone. These reporting-period figures are not added to the broader more-than-184,000 observation. The preceding IOM DTM update 12 reported a cumulative 152,856 people, or 25,476 households, displaced across seven governorates since the escalation began in June 2026. Within that earlier series, approximately 151,794 people, or 25,299 households, were displaced between 1 August and 29 September. The 22 September IOM DTM snapshot recorded 132,330 people, or 22,055 households, displaced cumulatively since June. All remain in the evidence history as dated observations. The earlier IRC report documented more than 80,000 people displaced after fighting escalated between Ansar Allah and the Internationally Recognized Government in early September 2026. The latest movement followed the fall of the strategic port city of Al Mokha, with many families forced to flee for the second time in a matter of weeks. Families arriving in host communities reported leaving belongings, livestock and livelihoods behind. Women, children and people with disabilities face heightened protection risks as access to essential services is disrupted. Schools are being converted into emergency shelters as the new school year begins, suspending children's education without a clear timeline for reopening. The IRC called on all parties to protect civilians and civilian infrastructure, allow safe and timely humanitarian access, and on donors to sustain and urgently increase emergency funding. The IRC is expanding cash assistance for displaced families in Aden and deploying mobile health teams across Aden, Lahj, Al Dhale'e and Abyan. Existing health, nutrition and protection services continue in Abyan, Al Dhale'e, Lahj and Shabwah, although access constraints limit the response. IOM said all newly displaced families need food, shelter and other basic assistance; a rapid protection assessment in three Ma'rib sites found unsafe shelter was the most critical vulnerability and that about 45 per cent of assessed households had been displaced before. On 2 October, WFP reported that renewed fighting had displaced more than 149,000 people, attributing the figure to IOM and noting that many had already experienced conflict-related displacement. This WFP-reported, IOM-attributed observation remains a separate series because WFP's release does not define its full geographic or time scope or link the underlying IOM DTM table. It is not arithmetically reconciled with IOM DTM updates or the new IOM observation and must not be read as 149,000 unique newly displaced people. WHO's Eastern Mediterranean office reported on 4 October that the escalation had caused 5,166 casualties, including 959 deaths, since 6 August. It recorded 685 new casualties during the preceding six days and said daily casualties in Taiz rose from eight to 109 within the week. WHO's casualty series is retained separately from IOM's displacement observations; no injury count is inferred by subtracting deaths from total casualties. International Medical Corps’ 8 October Situation Report #4 records a separate displacement series: 197,906 people from 29,519 families across 10 governorates since the escalation began, about a 10 per cent increase from its previous report. This IMC-reported observation is retained separately from the IOM DTM cumulative figure of 201,217 people / 33,535 households as of 6 October; the series have different source definitions and are not added, reconciled or substituted for one another. IOM DTM Update 15, published 21 October 2026 and covering data through 20 October, recorded 259,807 people (43,295 households) displaced cumulatively since the escalation began in June. Its separate 1 August–20 October reporting-period figure was 258,751 people (43,119 households). These are retained as dated earlier observations; neither is added to the current 24 October totals. The earlier 13 October observation of 228,739 people (38,122 households) remains preserved as a dated snapshot.

Armed violence in Petite Rivière de l'Artibonite displaces about 7,250 people

Armed violence that has occurred since 19 October 2026 in the commune of Petite Rivière de l'Artibonite, in Haiti's Artibonite department, has forced thousands of people from their homes. According to IOM's Displacement Tracking Matrix (DTM), the violence primarily affected the town centre of the 2nd communal section of Bas Coursin 2, as well as the locality of L'Amour within the same section, forcing several residents of these localities and surrounding areas to flee. Approximately 7,250 people (1,637 households) were displaced, according to DTM Emergency Tracking Tool 112, which is based on assessments carried out between 19 and 22 October 2026. Of those displaced, 60 per cent found refuge within Petite Rivière de l'Artibonite and 40 per cent in the neighbouring commune of Verrettes. Most, 86 per cent (6,215 people in 1,417 households), are staying with host families. The remaining 14 per cent (1,035 people in 220 households) settled in two displacement sites in Verrettes that already existed before these incidents: Parc Michelet Destinoble, which received 980 newly displaced people, and Ecole Flamboyant de Deschapelle, which received 55. The figures come from direct observations and/or interviews with key informants at displacement sites and in host communities, drawn from a DTM network of more than 5,000 key informants across Haiti. They describe displacement following these incidents only. The tracker does not report casualties, the armed actors involved or humanitarian needs. DTM says it continues to monitor the situation and will provide updates should there be any further developments. Source: International Organization for Migration (IOM), October 2026. DTM Emergency Tracking Tool 112. IOM, Haiti. IOM dates the report 22 October 2026; ReliefWeb posted it on 23 October 2026. Update, 24 October 2026 Haitian media reports and a police statement add detail to IOM's figures. Armed group: AlterPresse, Gazette Haiti and Le Quotidien 509 attributed the 19 October attack to the Gran Grif gang. The attack on the town centre began at about 3 a.m., AlterPresse reported. The mayor of Petite Rivière de l'Artibonite, Lereste Dort, said the police station and the town centre were the main targets, and he appealed for police reinforcements (Enfòmèm and Gazette Haiti, 19 October). Casualties: On 20 October AlterPresse reported, citing local sources, that at least three people were killed on 19 October. One man was killed in the town centre, and AlterPresse identified him only by his first name, Bruno. Two farmers were killed in their fields in Chandelle, on the boundary between Verrettes and Liancourt. Several members of community self-defence groups were wounded, but their injuries were not life-threatening. This is a preliminary toll from a single outlet. No UN or official casualty figure had been published by 24 October. Police response: Haiti's National Police said its Brigade de recherche et d'intervention (BRI) had launched an operation in Petite Rivière, removed barricades that armed groups had put up to block roads, and reinforced security in the town (AlterPresse, 23 October, citing a police note). Where people are sheltering: The 1,035 people in sites are at two sites in Verrettes that existed before the violence. Parc Michelet Destinoble in Savanne Bourg holds 980 people (205 households), and École Flamboyant de Deschapelle holds 55 people (15 households) (IOM DTM Emergency Tracking Tool 112). Wider picture: UN OCHA said on 23 October that this displacement, together with violence in Arcahaie on 18 October (nearly 2,900 people) and attacks in Gros Morne in late September (more than 10,000 people), had displaced more than 20,000 people in Haiti in less than a month. Most of them are staying with host families. OCHA said this places heavy demands on communities with limited resources of their own. A repeated pattern: IOM has recorded repeated displacement from Petite Rivière this year. Attacks in Petite Rivière and Dessalines between 28 March and 6 April displaced about 13,573 people. Needs: World's Aid found no published needs assessment or response plan for this displacement as of 24 October.

Stanford team finds a way to help bleached corals recover in weeks

A laboratory discovery at Stanford points to a new way to help bleached corals recover. In experiments, fragments from the same coral clone recovered fully within seven weeks after contact with a healthy counterpart. Beneficial algae and nutrients began moving between the coral tissues within three days.

7 weeksfull recovery in the laboratory
3 daysalgae transfer observed
5 dayscontact started recovery in some tests

The study offers a hopeful lead, but not a reef-scale treatment: each bleached coral would need a healthy, genetically identical partner. Coral reefs support food and livelihoods for hundreds of millions of people and help protect coastal communities from storms and flooding.
