IS suicide bomber hits Aden military camp

A man detonated his explosive vest among soldiers at the camp in the southern city of Aden overseen by the Saudi-led coalition, a military source said.

The soldiers were being trained by Sudanese forces belonging to the coalition, another military source said.

"So far, the bodies of nine soldiers and several wounded were brought to the hospital" in Aden, a medical source said.

The attack took place at the Ras Abbas military camp located in Aden's western Buraiqa district, the first military source said.

It comes just a day after Aden's governor and its police chief escaped unharmed from a gun attack on their convoy by al-Qaeda in the Arabian Peninsular (AQAP). 

Three of the attackers were killed and four guards protecting the convoy were wounded in a gunfight, according to the governor's aide.

Aden has seen a growing militant presence, with AQAP, long active in Yemen, and the Islamic State (IS) group apparently vying for influence.

The groups have claimed several attacks against government and coalition troops since the loyalists pushed the Shia Houthi rebels and their allies out of the port city and other southern provinces last July.

The Saudi-led coalition has been supporting President Abd Rabbuh Mansour Hadi's internationally recognised government with air strikes, weapons and troops since March last year.

The UN says more than 6,100 people have been killed and 29,000 wounded in Yemen's conflict since the coalition began its raids, about half of them civilians.
