A US drone strike has killed 13 suspected Islamic State group militants in central Yemen, security sources said Wednesday.
The strike in Bayda province would be the second known US strike against IS in Yemen.
The first came just over a week ago, when the US military said it had killed dozens of jihadists at IS training camps in the same province.
The United States is the only country known to operate armed drones over Yemen, but its previous known strikes have targeted Al-Qaeda.
IS has however risen to prominence in the country's civil war, targeting both government forces and Shia Houthi rebels, which it considers heretics.
