Unknown gunmen killed four paramilitary soldiers as they guarded a mosque in Pakistan’s volatile mega-city of Karachi Friday, officials said.

 

The killers, on three motorcycles, opened fire on the paramilitary Rangers outside the Abu Hurairah mosque in Ittehad Town, a western suburb of the southern city that is infested with Taliban-linked militants.

 

One of the Rangers survived the assault but died later of his injuries, officials said.
