Afghanistan's President Ashraf Ghani has appointed a commission to investigate an airstrike in northern Kunduz city that destroyed a hospital and killed at least 22 people.

Ghani's deputy spokesman Zafar Hashemi said on Saturday that the five-man team would leave soon for Kunduz to look into the cause of the Oct. 3 airstrike on a trauma center run by the international charity Doctors Without Borders.

He says the team will be led by the former head of the national intelligence agency Amrullah Saleh.

The airstrike was requested by Afghan ground forces, according to the commander of U.S. forces in Afghanistan, Gen. John F. Campbell, but mistakenly hit the hospital.

Military investigations are under way. The medical group has demanded an independent investigation that requires U.S. and Afghan cooperation.
