A drone strike killed five suspected Al Qaeda militants in Yemen's Marib province early on Sunday, security officials said.
One official said a US drone had probably carried out the strike, which targeted a car in the province's Saoud district.
Residents said the men's bodies were charred beyond recognition.
There was no immediate statement from the militant group or from US forces who have repeatedly launched drone and air strikes against Yemen's Al Qaeda affiliate, known as Al Qaeda in the Arabian Peninsula (AQAP).
The group has taken advantage of the ongoing war between Yemen's Houthi rebels and the government of president Abdrabu Mansur Hadi to strengthen its position in the impoverished country.
AQAP operates in several provinces in southern and eastern Yemen, including in Abyan, Shabwa and Al Bayda.
Washington's long-running drone war against AQAP has intensified since president Donald Trump took office in January.
An air raid he ordered that month killed a US Navy Seal and several Yemeni civilians in Al Bayda, just south of Marib.
