At least 25 people have been killed in a homicide bombing that struck civilians collecting humanitarian aid in Baghdad, Iraqi officials tell FOX News.

Police and hospital officials say Thursday's attack occurred near Tahariyat Square in the central neighborhood of Karradah.

The officials, who spoke on condition of anonymity because they weren't authorized to release the information, say women and children were among the dead.

An official at the Interior Ministry says 22 people have been killed and 52 wounded.

Violence across Iraq has fallen sharply over the least year but insurgents such as Al Qaeda continue to carry out frequent attacks.

A homicide bomber on Wednesday killed at least five people and wounded 15 inside a mosque in central Iraq, and on Monday, a homicide bomber in a police uniform killed four policemen in northeastern Diyala province. Eight U.S. soldiers were wounded.

Some expect violence could increase as rival political and armed groups position themselves ahead of a national election due to take place at the end of the year.
