Intelligence officials in Pakistan say a suspected U.S. drone strike near the Afghan border has killed at least one militant who is believed to be a foreign national.
Authorities say a missile hit the militant Sunday as he was riding a horse in the North Waziristan tribal belt, known as a stronghold of Taliban and al-Qaida militants.
The nationality of the insurgent was not immediately clear.
Local security officials say the drone strike killed two militants.
Pakistan has repeatedly criticized U.S. drone attacks as a violation of its sovereignty.
U.S. officials have said the strikes are an important tool in defeating militants.
