The deadliest of the day's attacks came shortly before sunset, when a bomb exploded in Baghdad's southeastern suburb of Jisr Diyala. Minutes later, a car bomb went off near the site of the first blast as people started gathering to help the victims of the initial explosion.
The casualty toll in Jisr Diyala rose throughout the evening, and within hours, police and hospital officials said that at least 25 people had been killed and that 50 were wounded, including several students who had just come out of a nearby school after class. The police sealed off the attack area.
The attacks are often claimed by the Islamic State group, which seized about a third of the country in a blitz last year, along with a swath of territory in neighbouring Syria.
Earlier today, a parked car bomb went off in a commercial area in the town of Mishada, 30 kilometres (20 miles) north of Baghdad, killing at least four civilians and wounding 12, police officials said.
