At least 33 people have been killed in a series of attacks across Iraq.
In the capital Baghdad, a car bomb exploded in a busy market near the al-Kamaliyah mosque.
The blast in the mainly Shia district killed 10 civilians and wounded a further 26.
A short time later, five people were killed when two more car bombs exploded near the nearby Sunni al-Samuri mosque in Baghdad's Jadida area.
The Samuri mosque is a short distance from the Kamaliyah mosque where the earlier car bomb was detonated.
In Riyadh, about 50km from the northern city of Kirkuk, two truck bombs exploded at a military base housing a unit that protects Iraq's oil infrastructure.
10 Iraqi soldiers died and six others were wounded in the attack.
The base is near pipelines which carry crude oil to the large Baiji refinery.
Elsewhere in Iraq, eight people were killed in various attacks, including five in the city of Baquba, northeast of Baghdad.
The continuing violence comes ahead of a 'national reconciliation conference' to be hosted by Iraqi Prime Minister Nuri al-Maliki.
The talks aim to bring the leaders of Iraq's sectarian factions together in an attempt to halt to the bloodshed.
However, the conference will be boycotted by a Sunni religious body, the Muslim Scholars' Association, which is accused of links with insurgent groups.
