Two rockets struck near Damascus airport at dawn on Friday, in an attack that is thought to have been carried out by Israeli warplanes from outside Syria's borders.
In a newsflash on screen, lLebanese television station Al Mayadeen said the rockets were probably fired from Israel but offered no further details. An Israeli military spokeswoman declined to comment on the reports of the air strike, saying: "We do not respond to such reports."
Earlier this month, the Syrian army reported an Israeli air strike on a military site in Syria's Hama province.
Israel says it has hit arms convoys of the Syrian military and its Iranian-backed ally Hizbollah nearly 100 times in the past five years. Israel, which fought a 2006 war with Hizbollah, sees the shipment to the powerful Shiite group of anti-aircraft missiles, precision ground-to-ground missiles and chemical weapons as a step too far.
The Syrian Observatory for Human Rights, which monitors Syria's civil war, said the attack earlier this month was on a facility of the Scientific Studies and Research Centre, an agency which the United States describes as Syria's chemical weapons manufacturer.
Syria's government denies using chemical arms. In 2013 it promised to surrender its chemical weapons, and insists it has stuck to that agreement.
