Eight killed, seven wounded. Authorities said they were warned of a possible al Qaeda attack:

A suicide car bomber blew himself up Monday at the site of an ancient temple popular with tourists, killing eight people and wounding seven, police said.

Police in the province of Mareb said six of the dead were tourists, believed to be mostly from Spain. The other two were Yemenis, police said, speaking on condition of anonymity because they were not authorized to speak to the media.

Witnesses said a car drive through a gate then exploded at the site of temple, which was built about 3,000 years ago at the time of the ancient Queen of Sheba.

No one claimed responsibility for the attack, but police in Mareb said they had received information last month about a possible al-Qaida attack.

Just a bumper sticker, huh?
