Israeli source says chemical weapons moved to new locations DAMASCUS, Syria, Dec. 9 (UPI) -- Israel has embarked on a covert war to monitor Syria's chemical and biological weapons, The Sunday Times of London reported. "For years we've known the exact location of Syria's chemical and biological munitions," an Israeli source told the newspaper, adding, " ... in the past week we've got signs that munitions have been moved to new locations." The "cross-border operation is part of a secret war to trail Syria's non-conventional armaments and sabotage their development," the newspaper said, adding special Israeli forces are operating as spotters to track the chemical stockpiles. The decision to conduct such a mission came after Israel rejected the idea of conducting an aerial or ground assault to destroy Syrian President Bashar Assad's stockpile of chemical weapons, mainly purchased from Russia, the newspaper said. If it becomes apparent that chemical weapons are being used by Assad, then Israel and the United States may coordinate to carry out a ground invasion, the paper said. There has been no Israeli government response to the report. U.S. officials said the White House and its allies are weighing military operations to secure Syria's stockpile of chemical weapons, Haaretz said. Israel has also been in contact with Jordan to coordinate the issue. Foreign Minister Nasser Judeh said his country is preparing "for different scenarios" and said the use of chemical weapons by Syria would be considered a "game changer." Syrian rebels Saturday captured a chloride factory at Al Safira east of Aleppo considered to be the country's biggest chemical weapons store and base, which also houses Syrian Scud D missiles armed with chemical warheads adjusted to fire at Israel, Debka.com reported. The fall of Al Safira into rebel hands crosses a red line and places the Assad regime in direct peril. Possession of the chemical-tipped Scuds gives the rebels their strongest weapon for forcing the Syrian army to capitulate," Debka said.
