At least 40 militants have been killed in a US air strike on an al-Qaeda training camp in south-eastern Yemen. Local officials and medics say another 25 militants were wounded when the camp in Hajr, west of the port city of Mukalla, was bombed yesterday. The US Defence department earlier said it estimated dozens of people had died. <br/><br/>Al-Qaeda in the Arabian Peninsula (AQAP) has exploited the current conflict in Yemen to expand the territory under its control. <br/><br/>Over the past year, the Houthi rebel movement and military units loyal to the former President have been battling a US-backed, Saudi-led coalition supporting the internationally-recognised government. Almost 6,300 people, half of them civilians, have been killed in the fighting.
