Pakistani intelligence officials say US missiles have killed three alleged militants in a tribal region along the Afghan border.
They say two drone-fired missiles hit a vehicle in the Baghar area of South Waziristan. The area has been used by militants to cross into Afghanistan, where many are involved in fighting US and NATO forces.
The two officials requested anonymity because they are not authorized to speak to the media.
It's the second missile strike since a US raid last week killed al Qaeda chief Osama bin Laden in Abbottabad, Pakistan, a garrison city that also lies in the country's northwest.
The raid heightened tensions between the two nations, but the United States has generally continued missile strikes even during sensitive times.
