Nicosia - Israeli forces carried out an air strike overnight on a weapons convoy from Syria near the Lebanese border, security sources told AFP on Wednesday, speaking on condition of anonymity.
The attack came after Israel expressed concerns that Damascus's stockpile of chemical weapons could fall into the hands of Lebanon's Shiite Hezbollah group, an ally of the Syrian regime, or other militant organisations.
Israeli officials have said such that a transfer would be a casus belli and likely spark an Israeli attack.
Sources differed on whether the strike took place on Syrian or Lebanese territory.
“The Israeli air force blew up a convoy that had just crossed the border from Syria into Lebanon,” one source said, adding that the convoy was believed to be carrying weapons, without specifying the type.
An Israeli military spokeswoman declined to comment on the report.
A second security source, speaking on condition of anonymity because of the sensitivity of the issue, also confirmed to AFP that Israeli warplanes had hit a convoy allegedly carrying weapons to Lebanon but said the incident occurred just inside Syria.
“It was an armed convoy travelling towards Lebanon but it was hit on the Syrian side of the border at around 2330 GMT,” the source said.
As well as concerns about Syria's chemical weapons stockpile, Israel has accused Syria of supplying long-range Scud missiles to Hezbollah.
It has also warned about the dangers of other advanced weaponry falling into the Lebanese militia's hands, such as anti-aircraft systems and surface-to-surface missiles.
Ahead of the strike, both sources reported a high level of “unusual” Israeli activity over Lebanese airspace, beginning on Tuesday evening and continuing overnight.
The Lebanese army said Israeli warplanes had entered Lebanese airspace up to 16 times between 9:30 am (0730 GMT) on Tuesday and 2:00am on Wednesday.
“Every day there are Israeli overflights, but on Tuesday they were much more intense than usual,” a Lebanese security source told AFP on condition of anonymity.
The attack took place just days after Israel moved two batteries of its vaunted Iron Dome missile defence system to the north and at a time of rising fears that the Syria conflict could see chemical weapons leaking into Lebanon.
Speaking to reporters in Jerusalem, a former intelligence chief with Israel's Mossad spy service said the Jewish state “should make any effort to prevent any weapons systems of that kind going out to terror organisations.”
In comments made before reports of the attack emerged, Amnon Sofrin said Israel was unlikely to hit chemical weapons stocks from the air because of the environmental risks.
“When you go and attack a... chemical weapons depot, you're going to do unwarranted damage because every part will leak out and can cause damage to many residents.
“But if you know of a convoy leading these kind of weapon systems from Syria to Lebanon, you can send a unit to the proper place and try to halt it” on the ground, he said.
On Monday, Israel's Maariv newspaper said that Prime Minister Benjamin Netanyahu had “urgently dispatched” his National Security Adviser Yaakov Amidror to Moscow to ask Russia to use its influence in Syria to prevent the transfer of chemical weapons. - Sapa-AFP
