The bomber had visions of paradise in his head, and a bundle of explosives and nails lashed to his body. He hit the detonator in a crowded Jerusalem pizzaria. Instantly, an aroma of tomato sauce was obliterated by dust and smoke and blood. The explosion killed 15 Israelis, including 7 children, and wounded scores more. Islamic militants from Hamas claimed responsibility, but Yasir Arafat paid the political price: Israel seized nine Palestinian Authority buildings, including Arafat's Jerusalem headquarters. Foreign powers, including the United States, protested the Israeli move. But in Jerusalem, many on both sides called for more blood.
