KARACHI, Pakistan -- Four suspected Taliban militants have been killed in a clash with security forces in Pakistan's southern port city of Karachi.
Local authorities told Radio Mashaal on March 10 that the four were killed by security forces in a special operation overnight.
Authorities said the militants had been involved in several terrorist attacks on security forces.
Pakistan has been conducting a large-scale antiterrorist operation in Karachi since September 2013 after Prime Minister Nawaz Sharif launched a campaign to fight violence, abductions, extortion and extremism.
Thousands of suspects have been arrested since then.
Human rights organizations have accused Pakistani security forces of allegedly killing suspected terrorists before trials or in staged gun battles, and of torturing suspects.
