Iraqi officials say 28 people have been killed by three bomb explosions in Baghdad.
Police say two car bombs detonated Monday amid a crowd of civilians. Then, a suicide bomber detonated explosives as police and others rushed to help the wounded.
It was the deadliest attack in the capital in months. The triple bombing left nearly 70 other people wounded.
No one has claimed responsibility. But attacks against civilians have been on the rise as al-Qaida in Iraq insurgents are pushed out of their strongholds.
The attacks on a busy street, in the Adhamiya district lined with shops and restaurants also damaged a bus carrying girls to school.
Also Monday, Iraqi police say a 13-year-old girl blew herself up at a security checkpoint in the Diyala province's capital, Baquba, killing four people and wounding 14 others.
Militants have increasingly recruited female bombers because they often can elude detection more easily.
Officials say the women and girls are vulnerable to recruitment, with insurgents playing on a sense of revenge for the death of the women's relatives.
Separately, the International Committee of the Red Cross opened a physical rehabilitation center Monday in the city of Fallujah, in Anbar province.
An ICRC rehabilitation specialist says the aim of the center is to help people disabled in the conflict reintegrate into society.
Fallujah was the scene of one of the bloodiest U.S.-led battles against Sunni insurgents during the Iraq war.
