Israeli jets struck seven crossing points along the Syria-Lebanon border on Friday, saying they aimed to cut off the flow of weapons to the Iranian-backed Hezbollah group in southern Lebanon.
Israeli troops also seized a truck mounted with a 40-barrel rocket launcher in southern Lebanon, part of a shipment from various areas that included explosives, rocket-propelled grenade launchers and AK-47 automatic rifles, the army said.
The commander of the Israeli Air Force, Major General Tomer Bar, said Hezbollah was trying to smuggle weapons into Lebanon to test Israel's ability to stop them.
"This should not be tolerated," he said in a statement.
Under the terms of the November 27 ceasefire agreement, Israel is supposed to withdraw its troops from southern Lebanon in stages, while Hezbollah's unauthorized military facilities south of the Litani River will be dismantled.
