Israeli warplanes carried out two airstrikes yesterday near Damascus, one near the city's international airport and a second outside a town close to the Lebanese border, Syria's state news agency said.

SANA called the attack "an aggression against Syria" and said there were no reports of casualties. The Israeli military said it does not comment on "foreign reports."

Syria's state news agency did not provide any details on what was hit near the Damascus airport or in the town of Dimas, which is located along the main highway from the Syrian capital to the Lebanese frontier crossing.

The Syrian Observatory for Human Rights, a Britain-based group that monitors the country's civil war through a network of activists on the ground, said the strike near the Damascus airport hit a warehouse, although it was unclear what was in the building.

The Observatory also said that around 10 explosions could be heard outside a military area near Dimas. It had no word on casualties in either strike.

Israel has carried out several airstrikes in Syria since the revolt against President Bashar Assad began in March 2011. Most of the strikes have targeted sophisticated weapons systems, including Russian-made anti-aircraft missiles and Iranian-made missiles, believed to be destined for Lebanon's militant Hezbollah group.

Israel has never confirmed the airstrikes.

While Israel has tried to stay out of the war in neighboring Syria, Prime Minister Benjamin Netanyahu has repeatedly threatened to take military action to preventSyria from transferring sophisticated weapons to its ally Hezbollah. Israel and Hezbollah are bitter enemies and fought an intense monthlong war in 2006.
