(Reuters) - More than 30 people died in a suicide attack and other bombings in northern Iraq and Baghdad on Wednesday, deepening sectarian strife in the OPEC nation as Prime Minister Nuri al-Maliki faces mounting pressure from minority Sunnis and Kurds.
Shoppers and police helped drag bloodied survivors out of the rubble and wrecked vehicles after a suicide bomber in a trunk set off a huge explosion in Kirkuk, near the local headquarters of the Kurdistan Democratic Party or KDP.
The attacks came as Maliki, a Shi'ite, is locked in a feud with ethnic Kurds in autonomous Iraqi Kurdistan over disputed oilfields and also is also confronting Sunni Muslim protesters in a western province calling for him to step down.
"A suicide bomber driving a truck packed with explosives detonated the vehicle outside the KDP headquarters. It's a crowded area, dozens were killed and wounded, Police Brigadier Sarhat Qadir told Reuters in Kirkuk.
