A car bombing in the Afghanistan’s central province of Ghazni killed at least 30 Afghan security force members on Sunday, officials said, and casualties could increase given the intensity and location of the blast.

Baz Mohammad Hemat, director of the provincial hospital in Ghazni, said 30 bodies and 24 injured people had been transported there. “All of the victims are security personnel,” he said.

The blast targeted a compound of the public protection force, a wing of the Afghan security forces, local officials said. It damaged civilian residences around the compound.

Interior ministry spokesman Tariq Arian confirmed that there had been a car bomb blast but did not provide further information on the target or possible casualties. No one has claimed responsibility for the attack.
