Sunnis v. Kurds

The Iraq civil war is growing a third leg. Violence is increasing between Sunni Arabs and Kurds in northern Iraq.

While the American military is trying to tamp down the vicious fighting between rival Arab sects in Baghdad, conflict between Arabs and Kurds is intensifying here, adding another dimension to Iraq's civil war. Sunni Arab militants, reinforced by insurgents fleeing the new security plan in Baghdad, are trying to rid Mosul of its Kurdish population through violence and intimidation, Kurdish officials said.

Mosul, Iraq's third largest city, with a population of 1.8 million, straddles the Tigris River on a grassy, windswept plain in the country's north. It was recently estimated to be about a quarter Kurdish, but Sunni Arabs have already driven out at least 70,000 Kurds and virtually erased the Kurdish presence from the city's western half, said Khasro Goran, the deputy governor of surrounding Nineveh Province and a Kurd.
