ADEN - The death toll in a suicide bombing at a local militia compound in the southern Yemeni city of Aden rose to at least 45, medical charity Medicins Sans Frontieres said on Monday.

A spokesperson for the group said at least 60 other wounded people had been brought into a hospital run by the charity in Aden.

A security official and witnesses said a suicide bomber drove a car into the building in north Aden. It was used by the Popular Resistance, a local force that had helped drive Houthis out of the city last year.
