An Israeli missile hit a convoy carrying medical supplies and fuel to an Emirati hospital in the Gaza Strip, killing several people from a local transportation company, the American Near East Refugee Aid group said Friday. Israel claimed without immediate evidence that it opened fire after gunmen seized the convoy.

The strike killed several people employed by a transportation company that the aid group was using to bring supplies to the Emirates Red Crescent Hospital in Rafah, said Sandra Rasheed, Anera’s director for the Palestinian territories.
