At least three armed men and three policemen, including a Deputy Superintendent of Police, were killed in a gun battle in Pakistan’s southern port city of Karachi on Wednesday, officials said.

The incident occurred near Safari Park in Gulshan-e-Iqbal Town area of the city. Sindh Police spokesman Imran Shaukat said three men were killed when they attacked police.

He declined to give the identity of the dead men.

Another police official said three personnel, including DSP Qasim Ghauri, died and two others were injured in the gun battle.

The official said the gun battle began after police launched a search operation in the area.

Karachi, a city of over 18 million, is in the grip of violence perpetrated by militants and criminals. So far, the Government has failed to control the bloodshed.
