BRUSSELS (AP) — Belgian prosecutors say police have shot and wounded a woman in Brussels after she attacked three people on a bus with a knife.

Brussels prosecutors said in a statement that the woman was shot by police for refusing to obey their orders. The incident happened in the Uccle neighborhood of the Belgian capital.

The statement said that "the victims and the suspect have been taken to hospital for treatment."

Belgian broadcaster VTM quoted an unnamed Brussels prosecutor as saying "we have no indication that this was going to be a terrorist act." It said that none of the victims was seriously wounded.

Belgium has been on alert since suicide bombings on Brussels' airport and subway killed 32 people on March 22. That attack was claimed by the Islamic State group.
