KAMPALA, Uganda (AP) — Ugandan officials say 32 people have now been charged in connection with the July bomb blasts that killed 76 people.

State attorney Joan Kagezi said Tuesday the suspects include nationals of Kenya, Somalia and Uganda.

Kagezi says four of the suspects have confessed. She says the suspects will have a hearing Sept. 2 but did not say when their trials might begin.

Police also say they are still investigating and there may be more arrests.

The al-Qaida-linked Somali militant group al-Shabab claimed responsibility for the July 11 bombings in two locations in Uganda's capital during the World Cup final.

Al-Shabab has vowed to attack Uganda and Burundi for sending troops to Somalia as part of an African Union peacekeeping mission.
