A double bombing tore through Kurdish political party offices in northern Iraq in the deadliest of a series of attacks nationwide that killed at least 33 people, officials said.
It was the second such assault in as many days. Nobody claimed responsibility for the attack.
But an al-Qaida splinter group known as the Islamic State of Iraq and the Levant claimed responsibility for the previous double bombing Sunday against Kurdish offices in Jalula, northwest of Baghdad, killing 19 people.
Iraq is grappling with its worst surge in violence since the sectarian bloodletting of 2006 and 2007, when the country was pushed to the brink of civil war despite the presence of tens of thousands of U.S. troops.
