Thirteen people have been killed and 18 wounded in a bombing at a crowded restaurant in Baghdad's district.
It is understood the restaurant was popular with police.
The bombing was one of a series of explosions in the capital a day after parliament approved the country's first full-term government since the US-led invasion of 2003.
Three civilians died and 24 were wounded when a roadside bomb went off in a busy commercial street in the capital's eastern New Baghdad district.
The bomb was apparently intended for a police patrol but the dead were all civilians.
And the northwestern Shula area, a car bomb killed three people and wounded six.
New Iraqi cabinet holds first meeting
The new Iraqi cabinet has held its first meeting after receiving parliamentary approval yesterday.
The broad coalition, still lacking permanent ministers in key security posts, is hoping to unite a country torn by continuing sectarian bloodshed.
The government of 37 ministers was approved after being presented to parliament by Prime Minister Nuri al-Maliki, who announced a national plan to bring Iraq out of its security crisis.
The unveiling of the new cabinet, after more than five months of fraught coalition talks, was welcomed by UN chief Kofi Annan, as well as the United States and its main coalition allies.
US President, George W Bush, said the future was a great challenge but there was an 'opportunity for progress'.
The protracted delay in forming a government had raised concerns that the power vacuum was allowing insurgents to seize the initiative.
However, the new line-up still lacks permanent appointments to the sensitive interior and defence ministries after persistent wrangling between Shia, Sunni and Kurdish politicians forced further negotiations.
In the meantime, al-Maliki will run the interior ministry while Sunni deputy prime minister designate, Salam al-Zaubai, will run the defence ministry.
