Authorities have served notices on residents of three villages in North Waziristan to leave their homes as a military operation is likely to be launched hours after a military convoy was attacked near one of the three villages, officials said on Saturday. The villages are Qutabkhel, Tolkhel and Chasma, the officials said. “We have served notices on residents of the three villages to leave homes as an operation can be launched any time,” they added. The notice was served four hours after a military convoy was attacked with a remote-controlled bomb near Chashma village causing damage to military vehicles and injuring two civilians. Local residents said people had started leaving their homes for fears of an operation by security forces.
