A Muslim 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.
According to the Hebrew Bible, the unnamed queen of the land of Sheba heard of the great wisdom of King Solomon of Israel and journeyed there with gifts of spices, gold, precious stones and beautiful wood to test him with questions, as recorded in First Kings 10:1-13 (largely copied in 2 Chronicles 9:1-12). The queen was awed by Solomon's wisdom and wealth, and pronounced a blessing on Solomon's God. Solomon reciprocated with gifts and "everything she desired," whereupon the queen returned to her country. The queen was apparently quite rich herself, as she brought 4.5 tons of gold with her to give to Solomon (1 Kings 10:10).
