We are deeply concerned about recent reports of escalating violence in Yemen and resulting deaths of civilians – including the attacks that killed an ambulance driver associated with Medecins Sans Frontieres in Dahyan, a freelance journalist near Sana’a, and civilians in Sana’a and at the Ras Isa oil terminal.  The United States takes all credible accounts of civilian deaths seriously and we again call on all sides of the conflict in Yemen to do their utmost to avoid harm to civilians and to comply with their obligations under international humanitarian law.
