ISLAMABAD, Pakistan (CNN) -- Two missiles fired from an unmanned drone struck a religious school in Pakistan's northwestern tribal region Thursday, killing eight people and wounding six others, military sources told CNN.
The sources -- who spoke on condition of anonymity because they are not authorized to speak to the media -- said the attack struck a village in North Waziristan, in an area believed to be a stronghold of veteran Taliban leader Jalaluddin Haqqani.
The attack came hours after Pakistan's parliament passed a resolution calling for a review of the country's national security strategy and stressing the need to revisit the way it was combating terrorism.
Lawmakers said dialogue ought to be "the highest priority" for managing the conflict and said the government needs to safeguard its sovereignty and territorial integrity.
"The nation stands united against any incursion and invasions of the homeland," the 14-point resolution said.
North Waziristan is a region rife with Islamic extremists near the Afghan border.
The United States is the only country operating in the region known have the capability to launch missiles from drones, which are controlled remotely.
The United States has in the past offered no comment on such strikes, citing policy.
Haqqani was among the mujahadeen fighters who received U.S. help to fight Soviet forces in Afghanistan in the 1980s. He has in recent years played a major role as a key Taliban commander in fighting U.S. troops in Afghanistan.
In September, missiles struck Haqqani's residence and madrassa, or religious school, killing two of his three wives and one of his sisters. Haqqani was in Afghanistan at the time and was not hurt.
Pakistan has repeatedly raised objections to foreign nations violating its sovereignty to pursue terrorists. A U.S. ground operation in September left several civilians dead and rankled relations between the two countries.
