An airstrike has killed three alleged al-Qaida fighters in the southeast of Yemen, accoring to a report.
Tribal witnesses told the Associated Press news agency that they suspected the strike on Tuesday was carried out by a US drone aircraft.
A Yemeni official said the government had not carried out any strikes in the area.
The tribal witnesses said the strike hit a vehicle carrying the three men in Hadramawt province, killing them.
The United States has regularly carried out drone strikes in Yemen, escalating the rate of attacks in the last year. Washington rarely confirms individual strikes.
