The exact site of the attack was not known, but according to officials it was very close to Kurram tribal district in the Federally Administered Tribal Areas (FATA) in restive northwestern Pakistan.
Hideouts of the Haqqani militant networks have been targeted in recent drone strikes in the region.
Four people were killed in the attack but the identity of those killed is not known, security sources said.
Foreign Office spokesman Mohammad Faisal said that it was not yet confirmed if the drone had hit targets inside Pakistan.
"The said press report (that drone hit Pakistan) is yet to be confirmed. We are checking with the relevant quarters," he said.
"Pakistan in principle has condemned the drone attacks as they are counter-productive and violate the sovereignty of Pakistan," Faisal said.
The Haqqani network has carried out a number of kidnappings and attacks against US interests in Afghanistan.
The group is also blamed for several deadly attacks against Indian interests in Afghanistan, including the 2008 bombing of the Indian mission in Kabul that killed 58 people.
In June, Afghanistan cut all cricketing ties with Pakistan after a deadly bomb attack which the country's intelligence agency blamed on militants backed by Islamabad.
The bombing in Kabul had killed at least 90 people.
Pakistan had rejected the Afghan allegations as "baseless".
