A suspected US drone strike killed eight people in northwestern Pakistan's tribal area, local officials said Friday.

The unmanned aircraft fired two missiles on a house at Mir Ali tehsil in North Waziristan tribal agency near the Afghan border, officials said.

On Thursday, another drone attack killed at least four people and injured five others in North Waziristan. Washington says insurgent fighters are hiding out in the area and planning attacks on Western troops stationed in neighboring Afghanistan.

The US drones regularly hit hideouts of the militants in the Pakistani tribal region, which Washington considers as the center of Taliban and Al-Qaeda militants. Pakistan opposes the US strikes inside the country and seeks the drone technology. But the US does not accept Islamabad's request.
