Israel is believed to have carried out hundreds of airstrikes against Iranian and Hezbollah targets throughout the Syrian civil war but has generally refrained from commenting about them for fear of being drawn into the fighting.
Only recently has it begun to speak publicly about thwarting the weapons smuggling from Iran through Styria into Lebanon. Israel's outgoing military chief, Lt. Gen. Gadi Eisenkot, did so over the weekend in various interviews.
Netanyahu says Israel says the recent strikes prove "we are committed more than ever to act against Iran in Syria."
Israel's military says its troops have found the sixth and the last tunnel dug by Hezbollah militants for cross-border attacks and that its operation at the Lebanese border is now over.
Military spokesman Jonathan Conricus says the final tunnel is the largest one discovered so far, running hundreds of meters (yards) from under a Lebanese home and deep into Israeli territory.
Israel launched the "Operation Northern Shield" last month to detect and destroy what it called a vast network of Hezbollah tunnels aimed for militants to sneak across the border and carry out attacks.
Israel and the United Nations say the tunnels violate a cease-fire resolution that ended a devastating war between Israel and Hezbollah in 2006. Conricus says the U.N. peacekeeping mission, known as UNIFIL, has been updated.
