A US drone strike targeting a militant compound killed six suspected rebels in North Waziristan near the Afghan border on Tuesday, security officials said. The strike took place in Miramshah Bazaar, part of the town of Miramshah, in the troubled North Waziristan region, known as a strong bastion of Taliban and al Qaeda linked militants. At least six militants were killed when a US drone fired two missiles on a rebel compound in the bazaar, a security official told a foreign news agency on condition of anonymity. He said thick smoke was seen coming out of the compound after the strike, adding the identities of those killed could not be immediately verified.
