Pakistan's military launched a ground offensive against insurgents in the Miramshah area of North Waziristan tribal region, killing at least 15 militants.
A statement issued by the Inter Services Public Relations (ISPR) said that three soldiers were injured in an exchange of fire between militants and security personnel.
According to Dawn, the army's infantry troops and Special Services Group (SSG) conducted door-to-door searches in Miramshah town to ensure that the civilian population had evacuated the area.
The ISPR further said that integrated fire of artillery, tanks and other heavy weapons is being carried out on terrorist concentrations in Mirali and other areas. Effective cordon is in place at other areas housing terrorists.
The military operation named 'Zarb-i-Azb' was initiated by the Pakistan army in the North Waziristan region in June.
Nearly 430,000 people have fled the region and sought refuge in the nearby areas of Pakistan as well as neighbouring Afghanistan.
