Several hundred inmates escaped after Taliban militants attacked a prison overnight, Afghan officials said, NBC News reported.
The siege began when a suicide bomber detonated a device near the gate of the main prison in Ghazni at around 2 a.m. local time, Deputy Provincial Gov. Mohammad Ali Ahmadi told NBC News.
"Very well-armed and well-organized" militants followed closely behind, he said.
The assault sparked a firefight, which lasted almost an hour and left at least four police officers and three attackers dead. Seven other officers were injured in the attack, according to Ahmadi.
