A drone strike on Sunday killed five suspected Al-Qaeda militants in the Yemeni province of Marib, east of the capital Sanaa, 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.
The US considers the Yemen-based Al-Qaeda in the Arabian Peninsula (AQAP) to be the radical group’s most dangerous branch.
AQAP has flourished in the chaos of the country’s civil war.
A long-running drone war against AQAP has intensified since US President Donald Trump took office in January.
An air raid he ordered that month killed a US Navy SEAL and several Yemeni civilians in Baida province, just south of Marib.
