A roadside bomb attack in east Baghdad, the Iraqi capital, has killed an army general, while violence in other parts of the city has left 13 others wounded, officials say.
Taha Ahmed Samir, a brigadier-general who headed training for Iraq's air force, was killed when a military convoy he was in was hit by a blast in al-Kanat street, an interior ministry official told the AFP news agency.
Two other soldiers were wounded in the explosion.
A separate blast in the Karradat Mariam neighbourhood, on the edge of Baghdad's heavily fortified Green Zone, left five people wounded, the official said.
He said that another explosion in Baab al-Muadham in central Baghdad wounded four other people.
On a street in the city's east, a policeman and a civilian were wounded by a bomb, a police official said.
While violence has dropped dramatically since its peak in 2006 and 2007, attacks remain common, especially in Baghdad.
In another development on Wednesday, hundreds of Iraqi workers rallied in central Baghdad, calling for improved salaries and better economic conditions.
The demonstration came after thousands of Iraqis had taken to the streets in recent days to protest against corruption, unemployment and the lack of public services.
At least 14 people were killed on February 25, which had been dubbed a "Day of Rage" by protesters.
