BAGHDAD (AP) -- Authorities in Iraq say at least 24 people have died in vehicle bombings in Baghdad and north of the capital.
At least 13 people were killed when an attacker drove his explosives-laden truck into a police station in a village near Samarra.
That bombing came hours after a suicide car bomber struck a police checkpoint in Saddam Hussein's hometown of Tikrit, killing three officers and one civilian.
In Baghdad, five people were killed by a parked car bomb at a market and police say two Iraqis were killed by a car bomb near the Polish Embassy.
Nobody has claimed responsibility for the attacks, but they bore the hallmarks of al-Qaida-in-Iraq, which has promised an offensive to coincide with the Islamic holy month of Ramadan.
