Officials say four people were killed and three injured when a US drone fired missiles at a house in a village in North Waziristan Agency, a Press TV correspondent reported.
Earlier in the day, six people were killed and another four wounded in a US air strike in neighboring South Waziristan agency.
Local residents stated that unmanned planes were still hovering in the area.
The US frequently carries out such attacks on Pakistan’s tribal areas.
The number of raids, initiated by former US President George W. Bush and expanded under President Barack Obama, has drastically increased in recent months.
The New York Times last year ran a report, saying the US government has ordered the CIA to step up air attacks in Pakistan. Washington claims its airstrikes target militants but civilians have been the main victims.
According to statistics, over 1,100 Pakistanis lost their lives in such attacks in 2010. The attacks have killed hundreds of civilians in Pakistan since 2008.
Pakistani officials say the unauthorized US drone attacks have proven counter-productive in the so-called fight against terrorism.
