KABUL, May 5 (Reuters) - Dozens of Taliban guerrillas ambushed an Afghan police convoy on Saturday, sparking a six-hour gunbattle in which eight officers were killed, police said. The clash, in the western province of Farah, saw 17 Taliban fighters killed or wounded, provincial police chief Sayed Agha Saqib said. Saturday also saw five separate suicide bombings in Afghanistan, most of them botched, but two Afghan police were killed in one attack, Afghan authorities said.
