Israel's prime minister is refusing to say whether his country carried out an airstrike against an alleged weapons shipment from Syria into Lebanon.
Standing alongside visiting German Chancellor Angela Merkel, Benjamin Netanyahu said Tuesday that Israel's policy is not to discuss what others claimed it did. He says "we do all that is needed to protect the security of Israeli citizens."
Lebanon's state news agency reported that Israeli aircraft carried out two airstrikes late Monday near the Lebanese-Syrian border.
Israel has refrained from taking sides in the Syrian civil war but has carried out several airstrikes on suspected shipments of advanced missiles believed headed for Hezbollah guerrillas. Netanyahu has vowed to prevent such arms transfers.
Israel and Hezbollah fighters fought a month-long conflict in 2006 that ended in stalemate.
