TL;DR
Ebola has now passed 1,200 suspected cases. The IRC is calling it the fastest-spreading outbreak on record and warning it could become the deadliest without urgent action. Uganda closed its border with DRC yesterday. In Gaza, a family of three including a six-month-old was killed in their apartment in Nuseirat while they slept, as 904 Palestinians have now been killed since the October ceasefire took effect. Russia struck the Chornobyl museum in Kyiv overnight Wednesday, a building that houses one of the most significant archives of nuclear disaster documentation in the world. A Haftar-aligned Libyan force detained members of a land convoy trying to bring aid into Gaza through Libya. And today, as Eid al-Adha begins, Palestinians in Gaza mark it for the third year without the ability to gather, travel, or mourn their dead.

1. Ebola: 1,205 suspected cases, Uganda closes its border, IRC warns of worst-ever outbreak
The numbers as of 27 May, per WHO and the DRC Ministry of Health: 1,205 suspected and confirmed cases, at least 264 deaths. Uganda confirmed seven cases including one death, five of them linked to the first two DRC-linked cases in Kampala, all among healthcare workers at a private hospital. On 27 May, Uganda closed its border with DRC for at least four weeks.
The IRC issued a statement this week describing the outbreak as spreading faster than the response, and warning it could become the deadliest Ebola outbreak on record without urgent international action. That's a significant statement. The deadliest on record is the 2014-16 West Africa outbreak, which killed more than 11,000 people across Guinea, Liberia, and Sierra Leone. The IRC's framing is not hyperbole — it is a direct consequence of the Bundibugyo strain's late detection, the conflict-driven inaccessibility of Ituri province, and the absence of any approved vaccine or treatment. Community resistance, including the burning of treatment tents I flagged earlier this week, is compounding the response challenge.
The US finalised plans on Wednesday to allocate an additional $80 million in bilateral assistance to partners on the ground, bringing total US Ebola response funding this cycle to over $100 million. The EU committed €15 million earlier in the week. The international response architecture is moving. The question is whether it's moving fast enough. Rwanda has introduced mandatory quarantine for returning travellers from DRC. Somalia issued a nationwide public health warning. Tanzania has tightened border checks. Hong Kong set up a quarantine facility on 19 May. Ten countries are now in the risk perimeter, per Africa CDC. The 2000 Bundibugyo outbreak in Uganda was contained at 149 cases in a rural district. This one is in three provinces, a capital city, and counting.

2. Gaza: 904 killed since October ceasefire, a family asleep in Nuseirat
On Sunday 24 May, an Israeli strike hit an apartment in the Nuseirat refugee camp in central Gaza. No warning. Mohammad Abu Mallouh, his wife Alaa Zaqlan, and their six-month-old son Osama were asleep. All three were killed. Around ten others in nearby buildings were wounded. Osama's uncle described finding them. The family had not been evacuated. They were at home. Gaza's Health Ministry says 904 Palestinians have been killed since the October 2025 ceasefire took effect.
Nine hundred and four since the ceasefire. The framing of a ceasefire as the baseline against which to count deaths is one of the more dispiriting features of this conflict's coverage. Overnight strikes on Nuseirat and Bureij camps on 23 May left residential areas in rubble and injured dozens, per Al Jazeera's footage from the scene. On 26 May, five Palestinians were killed in a strike on a refugee camp in central Gaza. Al Jazeera footage from the camp showed rescuers working through the debris of what had been a residential building.
The wider access and public health picture hasn't improved. Generators, engine oil, and spare parts remain restricted at crossings, driving system failures in health and sanitation. Only about 10% of the 2026 humanitarian funding requirement for the occupied Palestinian territory has been secured. Two NGO workers were killed in separate incidents in April, creating a staffing chilling effect on local partners. And today is Eid al-Adha. As millions of Muslims around the world gather to celebrate, Palestinians in Gaza mark it in displacement sites, without the ability to travel to family, buy food, or bury their dead with the rituals the occasion demands.

3. Libya: Haftar forces detain Gaza aid convoy
A brief item that deserves attention. Forces loyal to Khalifa Haftar, the Libyan National Army commander who controls eastern Libya, detained members of a land convoy attempting to bring aid to Gaza through Libya earlier this week. Al Jazeera reported the detention on 26 May. The convoy was part of a broader effort to use overland routes into Gaza as maritime and aerial routes remain blocked or contested.
The Libya dimension is worth holding. Haftar-aligned forces control most of eastern Libya and the Cyrenaica coast, which is one of the potential overland corridors for aid bound for Egypt and onward to Gaza. The detention of aid convoy members by a non-state armed group (and Haftar's LNA, whatever its formal relationship with Tripoli, operates as one in practice) adds another layer of obstruction to an already near-impossible supply chain. No further details on the status of the detained convoy members were available as of this morning.
It sits inside a wider pattern. The flotilla was intercepted in international waters. Crossing access from Egypt remains at 50-70% offloading rates. The UNRWA ban restricts agency operations. Now an overland route is being contested by a Libyan armed faction. The geography of the blockade keeps expanding.
4. Ukraine: Chornobyl museum struck, Kyiv takes another night of missiles
Russia struck Kyiv's Chornobyl Museum overnight on Wednesday. The museum, which houses one of the most significant archives of documentation from the 1986 nuclear disaster, sustained damage. No casualties were reported inside the building at the time. The strike follows last week's attack on the UNHCR-contracted warehouse in Dnipro, in which two workers were killed and significant pre-positioned humanitarian aid was destroyed.
The wider overnight picture from Wednesday into Thursday: Russian missiles and drones across multiple Ukrainian regions. The pattern this week has been the continuation of the large-scale aerial assault that began over the previous weekend, which OCHA described as one of the largest sustained attacks of the war. Civilian casualties have accumulated across Sumy, Kharkiv, Donetsk, Zaporizhzhia, and Kyiv oblasts throughout the week.
The Chornobyl museum strike is worth flagging on its own terms beyond the humanitarian angle. The museum is not a military installation. It is a cultural memory institution for one of the defining industrial disasters of the twentieth century, housing materials that document what happens when nuclear infrastructure fails and when governments conceal information from the people affected. That it was struck, whether deliberately or incidentally, in the context of a war that has repeatedly threatened the Zaporizhzhia nuclear plant, carries its own signal.

5. The week in numbers: what the system is carrying
Worth closing the week with the frame rather than another country story.
This has been one of the heavier weeks since we started the brief. Ebola declared a PHEIC eleven days ago and is now the third-largest outbreak on record. Somalia's WFP funding runs out in nine weeks. Sudan's appeal is 16% funded as the lean season begins. Gaza's humanitarian funding is at 10% of what's needed. Syria's bread subsidy, which fed four million people a day, is gone. Lebanon's death toll under a nominal ceasefire is approaching 3,000. The UNHCR warehouse in Dnipro was struck and two workers killed. A Gaza aid convoy was detained in Libya.
None of these are new crises. Most of them have been on this list since we launched. What's different this week is the accumulation: the sense that multiple files are moving in the wrong direction simultaneously, faster than the funding and the political will can catch up. The IRC's warning that the Ebola outbreak could be the worst on record isn't an outlier statement. It's a description of what happens when a global health emergency hits a conflict-affected province with no vaccine, no approved treatment, and a response architecture that's been running on reduced budgets for three years.
Tom Fletcher's line from the GHO launch is worth ending the week with: "If the world can spend $2.7 trillion on defence last year, surely it can spend just over one percent of that on helping the most vulnerable?" The $23 billion ask. One percent. The week's coverage is, in one way or another, a series of case studies in what happens when that one percent doesn't materialise.

That's the week. The Ebola file is the one to watch most closely over the weekend. Uganda's border closure and the IRC's warning suggest the next few days of case reporting will be decisive. Back Tuesday with the weekly round-up.
Have a good weekend.
