Pakistani gunship helicopters killed five insurgents while shelling militant hideouts near the Afghan border, officials said on Monday. Helicopters pounded militant bases hours after the main Taliban militant group, Tehreek-e-Taliban Pakistan (TTP) was banned and its bank accounts and assets frozen. "Helicopters gunships shelled militant hideouts in several villages in Bajaur Agency, which left five militants killed and 10 injured," a security official said on the condition of anonymity. The government rejected a ceasefire offer by the TTP in Bajaur on Sunday.
