A suicide bomber killed eight people Monday when he drove his car into the site of an ancient temple in Yemen's northeast province of Mareb, police said.
Police in Mareb said the suicide car bomb explosion also wounded seven other people. Six of the people killed 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 reported seeing a car enter a gate before exploding at the site of temple, which was built about 3,000 years ago at the time of the ancient Queen of Sheba.
No one immediately claimed responsibility for the attack, but police in Mareb said they had received information last month about a possible al-Qaida attack. Authorities did not elaborate.
