Outrage has erupted in Yemen over the killing of 13 civilians in a U.S. drone strike on Sunday. Yemeni government officials have confirmed the toll, saying the intended target of the strike was “completely missed.” According to CNN, outraged family members attempted to deliver the victims’ bodies to the residence of Yemeni President Abdu Rabu Hadi, but were denied entry. The Yemeni government says it is investigating.
