Earlier Wednesday, Lebanon’s military said 12 Israeli warplanes had violated Lebanese airspace in less than 24 hours, flying low in several sorties over villages in southern Lebanon.
The Israeli army said it would not comment on the reports, which followed several days of statements and high-level consultations on Syria among senior Israeli officials.
On Sunday, Israeli Vice Prime Minister Silvan Shalom told Army Radio that the movement of chemical weapons to Islamist rebels in Syria or to Hezbollah would be “a crossing of all red lines that would require a different approach, including even preventive operations.” He confirmed media reports that Prime Minister Benjamin Netanyahu had convened a meeting of top security chiefs last week to discuss developments in Syria and its chemical arsenal.
In public comments Sunday at the start of the weekly cabinet session, Netanyahu said Israel had to keep an eye on “lethal weaponry in Syria, which is breaking apart.” He added that there is “an accumulation of threats” for which Israel has to prepare.
Two Iron Dome missile defense batteries were positioned Sunday in northern Israel, in what the army called part of a routine rotation nationwide.
Many regional analysts say Hezbollah has not only restocked its weapons arsenal since the 2006 war but has also greatly expanded the supply and sophistication of its rockets. In a speech in May 2012, Hasan Nasrallah, the group’s leader, said Hezbollah could now launch rockets anywhere in Israel, and he later remarked that Syria had supplied the group’s most potent weapons.
Amnon Sofrin, a former director of intelligence for Israel’s foreign spy agency, the Mossad, told reporters in Jerusalem on Wednesday that with Syria in turmoil, Nasrallah was eager “to move to Lebanon everything he can under his custody.” Sofrin said Israel was watching carefully for convoys of weapons moving to Lebanon from Syria, where Hezbollah is thought to have stored some of its arms.
Mystery about motives
The Syrian assertion that Israel had bombed a research center deepened the mystery surrounding the possible motives for the attack. The official statement suggested that the target might have been a facility near Damascus operated by the Scientific Studies and Research Center, an arm of Syria’s armed forces that Western experts have linked to the country’s missiles and chemical weapons programs.
In 2005, the George W. Bush administration sanctioned the SSRC in an executive order, and two years later, the White House froze the assets of several of the center’s subsidiaries, on the grounds that SSRC scientists were seeking to develop “non-conventional weapons and the missiles to deliver them.”
Yet, military experts cautioned that there was no independent evidence that the facility had been bombed by a foreign air force. Syria may simply be trying to blame Israel for the loss of a facility that had fallen to rebels or been destroyed by other means, said Anthony Cordesman, a senior analyst at the Center for Strategic and International Studies, a Washington think tank.
“Would the Israelis have hit a facility that may have some chemical weapons in it? It’s doubtful,” said Cordesman, who co-authored a 2008 study of Syria’s weapons program. “If they did, Syria could respond by dispersing its arsenal further, which would increase the risk to Israel.”
On Wednesday morning, the Britain-based Syrian Observatory for Human Rights released a list of security incidents that included reports of shelling and a “huge fire” in the Jamraya area.
Rami Abdulrahman, who is the director of the monitoring group and who uses a pseudonym, said in an interview that reports about the incident were conflicting, with some local sources saying that it involved mortar shells and others alleging that Syrian airplanes struck the building.
