Syrian sources released on Sunday night a short video documenting the IAF strike on a security installation in the town of Dimas, one of the three targets that were bombed, according to Syrian reports, by Israeli Air Force warplanes. There were no casualties, according to the reports.
Earlier, Syrian television said that IAF warplanes attacked three targets on the outskirts of Damascus, two of which were near the international airport and in the town of Dimas.
"This direct aggression was undertaken to aid the terrorists in Syria after our forces claimed major victories in a-Zur and Aleppo."
"This aggression demonstrates Israel's direct involvement in supporting terrorism in Syria along with well-known regional and Western countries to raise the morale of terrorist groups, mainly the Nusra Front," the military said in a statement carried by SANA.
Salim Idris, former head of the Supreme Military Council of the Free Syrian Army, spoke to a subsidiary station of the Al Arabiya news channel, saying that the target of the alleged airstrike in Syria may have been shipments of weapons that were to be delivered to Hezbollah.
Since Syria's conflict began in March 2011, Israel has carried out several airstrikes in Syria that have targeted sophisticated weapons systems, including Russian-made anti-aircraft missiles and Iranian-made missiles, believed to be destined for Israel's arch foe – the Lebanese Hezbollah militant group.
Israel has never confirmed the strikes, and on Sunday the Israeli military said it does not comment on "foreign reports."
There is no evidence Israel has provided any support to the Nusra Front, which is al-Qaida's affiliate in Syria.
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 for imports and exports, 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.
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 prevent Syria from transferring sophisticated weapons to its ally Hezbollah. Israel and Hezbollah are bitter enemies and fought an intense monthlong war in 2006.
In May 2013, a series of Israeli airstrikes near Damascus targeted what Israeli officials said were shipments of Iranian-made Fateh-110 missiles bound for Hezbollah.
In eastern Syria on Sunday, Syrian warplanes carried out at least 11 airstrikes of their own against Islamic State militants attacking a key military air base, activists said.
The Islamic State group launched its assault on the sprawling air field just outside of the city of Deir el-Zour last week, touching off fighting that activists say has killed more than 150 people on both sides. For IS, seizing control of the base would eliminate the last significant government presence in the area and provide a major morale and propaganda boost.
The Local Coordination Committees activist collective and the Observatory said the strikes targeted four areas near the base.
After IS fighters succeeded in storming part of the base on Saturday, the Syrian military launched a counterattack – bolstered by heavy air raids – that managed to push the militants back. Scattered clashes on the ground continued Sunday with fighting on several fronts around the base, activists said.
