The death toll has risen to six following strike launched by U.S drones in Pakistan's northwest tribal area of North Waziristan on Friday night.

According to local media report, at least four U.S. drones were involved in the strike and three missiles were reportedly fired, two of which targeted a house in a village, one kilometer south of Miramshah, major city in North Waziristan.

U.S. drone strikes are designed to eliminate the militants hiding in the mountainous areas along the Pakistan-Afghanistan border, but many civilians have become the victims of such strikes.
