In fierce battles with Syrian troops, Al Qaeda’s al-Nusra front is spearheading the rebels’ advance on the Syrian army’s biggest chemical weapons depot at the Al-Safira base in the north. By Tuesday, April 2, the rebels were 1.5 kilometers from their target and Israel’s top security officials were on the Golan to inspect the IDF Golan border units’ state of readiness. On his first visit to the territory as defense minister, Moshe Yaalon said Israel would prevent the proliferation of weapons that “could threaten us.”
