At least four people have been killed during a non-UN-sanctioned US drone attack in Pakistan's northwestern tribal belt, security officials say.
A CIA-operated drone fired two missiles into Spalga village, 15 km south of city of Miranshah, in the northwest Pakistan's North Waziristan on Tuesday.
"It was a US drone strike, which targeted a militant's vehicle, killing four rebels," a senior local security official told AFP.
While Washington claims the air raids target militants, official figures have revealed that most victims are civilians.
US drones have launched around 30 missile attacks since early September.
An international group, known as the Campaign for Innocent Victims in Conflict (Civic), said in a report on Thursday that nine recent drone strikes in Pakistan had claimed the lives of more than 30 civilians.
The United States has intensified aerial attacks in Pakistan's tribal regions since US President Barack Obama took office in 2009.
This is while hundreds of Pakistani people have taken to the streets of the capital, Islamabad, to protest the unauthorized US drone attacks on the country's tribal areas.
The protesters condemn the killing of over two-thousand civilians in non-UN-sanctioned American drone strikes since 2004.
Activists have asked Washington to pay compensation to the families of victims and those who have suffered losses in such attacks.
The United States claims its drones target militant hide-outs near the border with Afghanistan.
According to official figures some 10,000 people have been killed in both Pakistani military operations and US drone strikes since former Pakistani military ruler Pervez Musharraf joined the so-called US-led war on terror following the 9/11 terrorist attacks in New York and Washington.
