The Lebanese army says the United States has supplied Beirut with two A-29 Super Tucano light-attack aircraft designed for counter-insurgency operations.
The army said in a statement that the aircraft were handed to Lebanon on Monday at the Hamat air base north of the capital Beirut. It gave no further details.
Washington has been a major supporter of Lebanon's army, which until recently had been fighting the Islamic State group and al-Qaida's Syrian branch on the border with Syria.
Last year, Washington delivered three Huey II helicopters, raising to 10 the number of such U.S.-made aircraft in Lebanon's fleet.
The U.S. has provided more than $1 billion in military assistance to Lebanon since 2006.
