NABLUS (AFP) - A Palestinian policeman fired on a group of Israelis in a Palestinian-controlled area of the West Bank on Sunday, killing one and injuring four, the Israeli army said. The shooting occurred early in the morning near Joseph's Tomb, a flashpoint shrine under Palestinian control and off limits to Israelis except on army-organised, escorted trips. In a statement, the Israeli military said Palestinian officials confirmed the shooter was a Palestinian policeman who opened fire "after identifying suspicious movements." Israel's Magen David Adom medical service said shots were fired at three vehicles, which evacuated to the nearby settlement of Har Bracha. "After attempts at reviving him, a man of around 30 years was declared dead. A young man of 20 was seriously injured and a youth of around 17 was moderately wounded. Two others were lightly wounded," the medical service said. One of the men hurt in the attack suffered a gunshot wound to the stomach and was in serious condition, while the second was shot in the shoulder and was in moderate condition, hospital medics said. The Israeli army, citing an account of the incident given by Palestinian officials, said the men went to the site without permission. "The civilians were shot by a Palestinian policeman who, after identifying suspicious movements, fired at their direction," a statement said.
