Syria said Israeli forces launched simultaneous missile attacks on the airports in its capital Damascus and the northern city of Aleppo on Thursday, damaging the runways and putting both hubs out of service.
A Syrian military source cited by state news agency SANA said "bursts of missiles" hit the two airports at the same time, in what he said was a bid to distract the world's attention from Israel's war with Hamas militants in Gaza.
The Israeli military said it does not comment on such reports.
Israel has for years carried out strikes against what it has described as Iran-linked targets in Syria, including against the Aleppo and Damascus airports.
Sources have said strikes on the airports are intended to disrupt Iranian supply lines to Syria, where Tehran's influence has grown since it began supporting President Bashar al-Assad in the civil war that started in 2011.
Thursday’s strikes came a day before Iran’s foreign minister, Hossein Amirabdollahian, was due to visit Syria.
Israel has vowed to annihilate the Hamas movement that rules the Gaza Strip, in retribution for the deadliest attack on civilians in its history when hundreds of gunmen crossed the barrier and rampaged through Israeli towns on Saturday.
Tehran has celebrated the Hamas attacks but denied being behind them.
On Tuesday, Israeli troops fired artillery and mortar shells towards Syria after rockets from southern Syria hit Israeli positions across the border.
