The attacks took place in the Khyber tribal region, which has been rarely struck by American missiles before over the last three years. That could indicate a possible expansion of the CIA-led covert campaign of drone strikes inside Pakistani territory.
The Obama administration has intensified missile attacks in northwest Pakistan since taking office, desperate to weaken insurgent networks there that US officials say are behind much of the violence against US troops just across the frontier in Afghanistan.
The first strike targeted two vehicles in the Sandana area of the Tirah Valley, killing seven militants and wounding another nine. The men were believed to belong to the Pakistani Taleban, one of the country’s largest and deadliest insurgent groups.
Later, missiles hit a compound in Speen Darang village where the Lashkar-e-Islam, a Taleban affiliate known to be strong in Khyber, were meeting, killing 32 people, among them commanders. The third strike took place in Narai Baba village and killed 15 militants, the officials said.
The officials spoke on condition of anonymity because they were not authorized to talk to the media.
US officials do not acknowledge firing the missiles, much less comment on who they are targeting. It is impossible to independently report on the aftermath of the attacks because outsiders are not allowed to visit the tribal regions. Human rights groups say there are significant numbers of civilian casualties in the attacks.
Most of the more than 100 missile attacks this year inside Pakistan have taken place in North Waziristan, which is effectively under the control of a mix of Taleban, Al-Qaeda and related groups. The region, seen as the major militant sanctuary in Pakistan, has yet to see an offensive by the Pakistani military.
