A US missile slammed into a car killing four militants at dawn Monday in Pakistan's remote tribal belt near the Afghan border in the third attack in a week, Pakistani officials said.
The strike from a suspected US spy plane was similar to an August 5 attack that killed Baitullah Mehsud, the head of Pakistan's Taliban.
It was the third such strike since last Monday in North Waziristan.
The drone fired a missile into a vehicle in Toori Khel village, the Pakistani officials said.
"Four militants were killed," a local government official said, requesting anonymity. Another security official said four people were wounded.
"The missile was fired from a US drone," he said.
Residents said the vehicle was parked outside a building and was preparing to leave when it exploded in a fireball in a massive blast.
"We were sleeping in our home after performing dawn prayers when we heard a huge blast. Children started screaming and we thought it landed in our home," local resident Haider Khan told AFP by telephone.
"Later on, I found out it landed about 500 meters away, " he added.
"Its occupants died and four others, who were apparently there to see them off, were wounded," said Ameerullah Khan, telling AFP by telephone that he lived a "two-minute drive" from the site of the strike.
"I saw from the roof of my home the blown-up car. Flames continued to rage for almost half an hour after the strike," he added.
A similar attack in the area killed three people last Tuesday. One day earlier, a strike targeting a madrassa religious school and an adjoining house killed five people.
The US military does not, as a rule, confirm drone attacks, but its armed forces and the Central Intelligence Agency operating in neighboring Afghanistan are the only forces that deploy pilotless drones in the region.
Islamabad publicly opposes the US missile strikes, saying they violate its territorial sovereignty and deepen resentment among the populace. Since August 2008, nearly 60 such strikes have killed more than 550 people.
Some analysts believe, however, the government tacitly supports the attacks, as it shares the US goal of "eliminating" Mehsud's network.
"Such attacks are conducted under mutual exchange of intelligence between Pakistan and the United States," said Rahimullah Yusufzai, a tribal affairs expert and Pakistani analyst.
