Yemen PM bin Breik quits, replaced by foreign minister

Yemen has been a ‍source of heightened tensions in recent months between Saudi Arabia and the United Arab Emirates.

A UAE-backed separatist group, the Southern Transitional Council, gained control of areas ​across southern and eastern Yemen ‌in December, advancing to within reach of the Saudi border, which the ​kingdom considered a threat to its national security. ‍Saudi-backed fighters have since largely retaken those areas.

Sharp differences over a range of other issues ​from geopolitics ​to oil output ​have also been a ​cause of friction between the two Gulf powers.

Saudi Arabia and the UAE had previously worked together in a coalition battling the Iran-backed Houthis in Yemen's civil war, which brought on one of the world's worst humanitarian ‍crises.
