Syrian state media reported the strike on the container yard at Latakia port without specifying what was targeted.
The Observatory, a UK-based organization with a wide network of sources on the ground across Syria, said the raid triggered a series of explosions.
It reported "huge material losses" but added there were no immediate reports of casualties.
According to the Syrian state news agency SANA, the strike occurred at 1:23 am (2323 GMT Monday).
"Our air defenses repelled the Israeli aggression in Latakia," it said, adding that a number of containers caught fire in the strike.
Latakia is the northernmost of Syria's main ports, and lies around 230 kilometers (140 miles) north of Damascus.
Photos and footage published by SANA showed a fire in the yard but state television

said later that firefighters had brought the blaze under control.
Israel rarely comments on the air strikes it carries out in Syria but has said repeatedly it will not allow its archfoe Iran
...a theocratic Shiite state divided among the Medes, the Persians, and the (Arab) Elamites....to extend its footprint in Syria.
