A five-hour police shootout with a leftist militant in Istanbul left three people dead, including the militant described as a top member of a group tied to the Kurdish separatist PKK, authorities said. A police officer and an onlooker also were killed, and seven police and a television cameraman were wounded, Interior Minister Besir Atalay said. The clash began with a dawn police raid at an apartment building in Istanbul's Bostanci district. The militant responded by throwing two explosive devices that wounded several officers, Gov. Muammer Guler of Istanbul said.
