ADEN: An Islamic State group militant rammed his explosives-laden car into an army recruiting center in Aden on Monday, killing 71 people in the deadliest jihadist attack on the Yemeni city in over a year.

The army, supported by a Saudi-led coalition, is training young recruits to join its nationwide war against Shiite Huthi rebels and their allies, as well as Sunni jihadists.
