Fresh bombs in the Iraqi capital have killed at least eight people, hours after dozens died in a suicide attack.
Most of the victims of Sunday's four blasts were policemen - three from an elite commando unit. Many were injured, including a number of civilians.
The new attacks came as chilling details emerged of Saturday's suicide bomb in Musayyib, south of Baghdad, which killed 90 people and injured 156.
Reports say parents threw children out of burning houses to save them.
It was the worst attack since a massive car bomb killed at least 114 people in the nearby town of Hilla in February.

Saturday's bomber blew himself up near a mosque in the town, which is ethnically mixed but predominantly Shia.
The blast caused a nearby fuel tanker to explode, causing a huge explosion and fireball which engulfed people, vehicles and buildings.
At the time, the streets were filled with cars and pedestrians, people coming out as the intense heat of the day subsided. The town centre has been devastated.
"I was 100 metres (yards) away when I saw the fireball. It was enormous... People were burning in their cars," witness Khodr Abbas told the AFP news agency.
"I saw women in the burning houses crying for help and we couldn't do a thing," he said.
The militant group al-Qaeda in Iraq has said their leader Abu Musab al-Zarqawi has urged them to intensify their attacks.
On Sunday, a car bomb in southern Baghdad killed two police commandos and a civilian and injured 13, including nine policemen.
Another bomb in the west of the city killed a commando and wounded three civilians.
Four more policemen died in another two bomb attacks in the city.
Many civilians were wounded in Sunday's attacks
This latest wave has come just as the Americans were claiming some success in reducing the number of car bombs, the BBC's Jon Leyne says.
However, in response, the bombers have changed their tactics as well, our correspondent says.
Some suicide bombers are sent on foot, with the explosives strapped around their waists, to attack targets protected against car bombs, as was the case in Musayyib.
