On 15 May 2016, a suicide bombing in the southern Yemeni port city of Mukalla, the capital of the Hadhramaut province, killed at least 47 police and injured over 60. The bombing was preceded by an attack, where 15 Yemeni troops were killed in attacks on army positions outside Mukalla. ISIL said, one of its militants blew up a vehicle, packed with explosives, in an army base in the Khalf district at the city's eastern outskirts.
