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 defence 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 Jamal al-Aqel,, the Abyan governor, 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. A local official said charred bodies were strewn around the site of the blast in which Abdul Latif Al Sayed, the leader of tribal fighting units known as "Popular Committees", who has previously survived assassination attempts. "Bodies were flying in all directions because the explosion was so powerful," he said.
