DRC Ebola outbreak carries up to 50% death rate

The WHO has confirmed a fatality rate of between 30 and 50 percent as its director general travels to the affected region.

The World Health Organization has confirmed that the current Ebola outbreak in the Democratic Republic of the Congo is killing between three and five in every ten people infected, a mortality rate that officials have described as alarming even by the standards of a disease long associated with devastating lethality. The revised estimate, which is based on confirmed cases, was communicated to reporters in Geneva by Anaïs Legand of the WHO's high threat pathogens team, who noted that the true scale of the outbreak is believed to be considerably larger than official figures suggest, given that the virus appears to have circulated undetected for some time before the outbreak was formally declared on 15 May. More than 1,000 confirmed and suspected cases have been recorded to date, with 10 confirmed and 223 suspected deaths among them.…

  • Why might conflict and displacement make it so much harder to contain an Ebola outbreak?
  • What does a 30 to 50 percent death rate tell us about the severity of this particular strain?
  • How significant is it that the WHO opposes travel bans as a response to disease outbreaks?
  • What challenges might health workers face when operating near active armed conflict zones?
  • Why could the true number of cases be significantly higher than the figures currently recorded?

Gaza cemeteries erased by Israeli military operations

Satellite imagery updated on Google Earth has revealed that at least 94 percent of Gaza's cemeteries have been fully or partially destroyed during the ongoing Israeli military campaign, according to the Euro-Med Human Rights Monitor. The Sheikh Mohammed cemetery in Khan Younis, where Palestinian journalist Muhannad Qishta's sisters are buried, has been replaced by an Israeli military outpost, a transformation that he described as emblematic of a war in which even the dead have not been spared.

The high-resolution images, captured in February 2026, document the near-total erasure of entire residential neighbourhoods across Gaza, including the Saudi neighbourhood in Tal as-Sultan in Rafah, a 752-unit housing project that has been reduced to rubble, and the Swedish village on the coast, which was founded in 1965 to shelter Palestinian refugees and has since been converted into a military zone. For many Palestinians, the updated maps are understood to offer a wide-angle record of destruction that has killed nearly 73,000 people.

Anthropic surpasses OpenAI with $965bn valuation

Anthropic, the company behind the Claude AI assistant, has raised $65 billion in a new funding round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, placing its post-money valuation at $965 billion and making it the most highly valued AI startup in the world, ahead of its rival OpenAI. The growth is widely attributed to the widespread adoption of Claude by large enterprise clients, particularly following the release of powerful coding tools late last year, which repositioned the company from a relatively niche player into a dominant force in the industry.

The funding announcement arrives against a backdrop of considerable legal and political turbulence for the firm, which remains in dispute with the Pentagon after refusing to remove safeguards that would have allowed its models to be used for mass surveillance or lethal autonomous weapons systems. Anthropic has also been reported to have withheld the release of its latest Mythos model over cybersecurity concerns, a decision that is said to have prompted a degree of geopolitical tension and temporarily eased the White House's broader confrontation with the company.
  • How might Anthropic's safety-focused positioning affect its relationship with governments seeking military AI applications?

4CRITICAL THINKING
Both the Ebola and Gaza articles describe situations in which conflict is directly worsening a humanitarian crisis. To what extent do you think the international community has a responsibility to intervene when warfare prevents aid from reaching civilian populations? Consider the roles of organisations such as the WHO and the Euro-Med Human Rights Monitor in shaping public pressure.
