The Pakistan Army carried out a major operation against Baloch nationalists and anti-government tribesmen in southwestern Balochistan inflicting casualties, reports said on Saturday.
The operation was launched on Friday against the members of the Marri tribe in Kohlu and Sibi districts and the forces destroyed at least four camps of tribal militants.
There were conflicting reports on casualties. A spokesperson for the 'Anjuman Ittehad Marri' claimed that 18 people were killed in the military operation.
Others spoke of 16 deaths. The dead and injured included women and children.
The security forces began the crackdown in Babar Kach, Jalari, Sangan and Pir Darbar areas in the morning, sources said.
They said helicopter gunships were seen targeting the camps of miscreants, known as 'farari' camps.
However, a spokesperson for the provincial government Abdur Razaq Bugti denied that any major operation had taken place.
