Suicide bombers kills 45 in Yemen, weeks after army declared victory

A suicide bomber struck at a wake in Yemen's southern city of Jaar overnight, killing at least 45 people and wounding dozens more, the defense ministry said, in the deadliest attack since the army declared victory over Islamist militants in June.

The bomber appeared to have been targeting the head of a group of tribal fighters that sided with the Yemeni army during an offensive that drove Al Qaeda-linked militants from their strongholds in the southern province of Abyan.

"This is a cowardly, criminal, terrorist attack," said Abyan governor Jamal al-Aqel, adding that an investigation was underway to determine the bomber's identity.

The attack highlighted the enduring threat of Islamist militancy in Yemen and may alarm the United States and Saudi Arabia, which increasingly view the impoverished state as a front line in their war on Al Qaeda and its affiliates.

Further east in the province of Hadramout, a US drone fired on a vehicle ferrying suspected militants, killing its three passengers, a local official said.

Ansar al-Sharia (Partisans of Islamic Law) seized several towns in Abyan last year, establishing a foothold there while then-President Ali Abdullah Saleh was grappling with mass protests that eventually toppled him.

The United States supported the Yemeni military campaign through which the army regained control of territory it had lost, but residents and analysts say the militants are simply lying low and waiting for a chance to regroup.

"A number of individuals from these gangs took refuge in the mountains next to the north of Jaar after the big defeat they were dealt by the army and Popular Committees," said state news agency Saba. "Today they resume their cowardly suicide operations."

Despite losing their territorial base, militants have shown they still pose a considerable threat, assassinating a top southern military commander, and killing four policemen in an attack on Jaar police station just last week.
