Armed men have attacked a police compound in the southern Pakistani city of Karachi, officials say.
Gunfire and explosions were heard on Friday outside the premises, which is home to several police buildings and officer residences, local media reported.
Tehreek-e-Taliban Pakistan (TTP), also known as the Pakistani Taliban, claimed responsibility for the attack.
Interior Minister Rana Sanaullah Khan said five or six gunmen were involved in the attack and threw hand grenades as they tried to force their way into the police headquarters.
Sharjeel Memon, the spokesman for Sindh province, said the attackers were surrounded although fighting was still under way.
At least two of the attackers were killed, police officials said. (Aljazeera)
