Israeli aircraft fired two missiles at targets near Damascus international airport overnight Monday, Syrian state news agency SANA reported Tuesday.
The Israel Defense Forces neither confirmed nor denied the report, with an Israeli military spokesman saying, "We do not comment on foreign reports."
The U.K.-based Syrian Observatory for Human Rights monitoring group reported on the incident, saying that Syrian air defenses failed to intercept the missiles.
The group said an explosion was heard at 1 a.m. near the airport and that the strike "targeted a weapons depot and warehouses belonging to non-Syrian militias loyal to the [Syrian] regime."
The Observatory said it had no information about casualties or damage.
Russian news website Sputnik reported that the strike took place north of Quneitra province, southwest of Damascus – closer to Israel – and targeted an Iranian cargo plane.
The Beirut-based Al Masdar news agency claimed the strike came as retaliation after a Syrian drone tried to infiltrate Israeli airspace on Sunday.
SANA pointed the finger at Israel.
"This strike is part of the support Israel gives to terrorist groups [fighting Syrian President Bashar Assad] in an effort to boost their morale after the heavy losses they were dealt by the Syrian army," it said.
"There is evidence showing the close ties between these terrorists and the Israeli enemy, which supports them directly after every blow they suffer by Syrian forces."
Iran is a key ally of Assad's and also backs a number of militias, including the Lebanon-based Shiite terrorist group Hezbollah, that are fighting in Syria in support of Assad.
Concerned that Iran's growing presence in Syria is a threat to its security, Israel has struck dozens of Iranian and Iran-backed positions in Syria over the course of the seven-year conflict.
