"The (Israeli Air Force) conducted an intelligence-based strike in Damascus targeting Hezbollah's representative to the Syrian military, Salman Nemer Jomaa," the military said, adding he played a key role in weapons deliveries between Syria and the militant group.

"As part of his duties, Jomaa was responsible for coordination between Hezbollah agents and the Syrian army, including to support the smuggling of weapons between Syria and Hezbollah," it added.

Syrian state news agency SANA had reported an Israeli strike on a car on the road to Damascus's international airport, while a war monitor reported one person killed.

"A car exploded after it was targeted in an Israeli aggression on the road to Damascus International Airport," SANA reported, citing a police source.

According to the Britain-based Syrian Observatory for Human Rights, the car was targeted by an Israeli drone.

"A man who was inside was killed and another was injured," said the Observatory, without providing details of their identities.

The strike occurred near a military airfield, added the Observatory, which relies on a network of sources inside Syria.

Since Syria's war broke out in 2011, Israel has carried out hundreds of strikes in Syria, mainly targeting the army and Iran-backed groups including Lebanon's Hezbollah.

Israel rarely comments on such strikes but has repeatedly said it will not allow Iran to expand its presence in the country.

The strike on Damascus came amid mutual accusations between Israel and Hezbollah of violating the ceasefire that came into effect in Lebanon on November 27.
