Iraq bombs: Police targeted in capital Baghdad
Two suicide bombers detonated explosives-laden vehicles minutes apart in north-western Hurriya district and central al-Wiya district, reports said.
They killed 22 and at least another six died in other bombs, police said.
The resurgence of suicide attacks inside the capital is a worrying development even by Iraqi standards, says the BBC's Rami Ruhayem in Baghdad.
It comes as the last US troops prepare to withdraw by the end of the year.
Police targeted
In Wednesday morning's attacks, one of the suicide bombers struck at al-Wiya police station, located at one of Baghdad's main road junctions.
Another drove his car into the police checkpoint in the Hurriya neighbourhood, a busy residential area - and reportedly a stronghold of Shia cleric Moqtada al-Sadr - which is surrounded by blast walls.
More than 50 people were injured in those two attacks; Kazinform cites BBC.
