Two Syrian jets crossed into Lebanese territory and dropped bombs on a town, Lebanon's Daily Star, citing senior security sources, reported Monday.
It marked the first airstrike in Lebanese territory since the uprising in Syria began 18 months ago.
The soviet MiGs reportedly fired three missiles at populated fields in Khirbet Dawoud, causing damage to farmhouses but no casualties.
Lebanese President Michel Sleiman confirmed the incident, telling a Cabinet meeting, “an attack occurred today on Khirbet Dawoud in the border Arsal region. Investigation is still ongoing in this regard to take the necessary measures."
The Arsal area shares 50 km of border with Syria and is believed to be the main point for arms smuggling between the two countries.
