Violence in split Arab-Kurdish city causes concern

"A suicide bomber attacked mourners at a Kurdish funeral in a town north of Baghdad, killing at least 25 and injuring at least 45 in the worst of a series of four bombings around Iraq Monday. Altogether, 37 people were killed and 60 were wounded in the attacks," Laith Hammoudi and Leila Fadel report for McClatchy Newspapers.

"The violence reflects rising tensions between Iraq's Kurds and Sunni Muslim Arabs. Kurds want to incorporate lands that the Arabs controlled during Saddam Hussein's dictatorship into the semi-autonomous Kurdish region in northern Iraq. Arabs are angered by what they consider Kurdish efforts to annex Arab lands along a 300-mile strip from the Syrian border to Diyala province, and especially the oil-rich city of Kirkuk.
