Speaking on the condition of anonymity, some Israli officials said on Saturday that the Israeli fighter jets targeted a shipment of weapons in Syria on Friday.
They said that the attack was approved during a secret meeting of Prime Minister Benjamin Netanyahu's security cabinet on Thursday night.
There have been no immediate comments from Syrian officials.
Earlier Saturday, two US officials also said that the Zionist regime "most likely" conducted an airstrike on Syria "in the Thursday-Friday time frame", claiming however that the regime's fighter jets "did not enter Syrian airspace".
CBS News also cited US sources as saying the Israeli warplanes targeted "a warehouse."
The CNN news channel also reported that the Pentagon had collected information showing Israeli warplanes overflying Lebanon during the time frame of the strike.
US Republican Senator Lindsey Graham of South Carolina also confirmed that Israeli warplanes attacked Syria.
In January this year, Israeli warplanes also targeted a research facility on Syrian soil.
