The latest round of United States airstrikes in Yemen have killed dozens of people in a port in the country's northwest, according to Houthi rebels. The strikes are part of an escalating campaign by the Trump administration against the Iran-backed militia. The American bombardment targeted the port of Ras Isa, a major fuel depot in the Houthi-controlled province of Hudaydah. The strikes have yet to deter the Houthis from carrying out further attacks, and experts warn that attacking ports could worsen the already dire humanitarian crisis in Yemen.
