PESHAWAR, Pakistan — Two people suspected of being militants were killed Sunday morning in the volatile North Waziristan tribal region by what Pakistani and Taliban officials said was a drone strike.

If confirmed, the attack could be the first American strike in Waziristan in two months — one of the longest operational pauses since the drone campaign started in earnest in mid-2008. American and Pakistani officials are at odds over whether two previous attacks this year were American drone strikes or some other kind of violence.

Two Pakistani officials, one in Peshawar and another in the tribal belt, said that missiles fired from a drone operated by the C.I.A. hit the two people in the village of Degan, about 20 miles from Miram Shah, the main town in North Waziristan.

“Details are sketchy,” the senior official in Peshawar said, speaking on the condition of anonymity. “We don’t know the identity of those killed, and our local contacts say the bodies were unrecognizable and beyond recognition. We don’t know if they were locals or foreign militants.” That official said the two people who were killed had been traveling on a motorcycle when the missile struck, but the official in the tribal belt said they were on horseback. There were some reports that three people were killed in the attack.
