"In Iran today they… are trying to boast about the new missile. Iran openly declares its intention to destroy the State of Israel. I have a clear message to the tyrants of Tehran: We know what you are doing and where you are doing it. We will continue to take action against Iran with all the tools at our disposal in order to ensure the security and future of Israel," the prime minister said at a cabinet meeting, as quoted by his press service.
"Iran has proxies. One of them is Hezbollah. Hezbollah just joined the government of Lebanon. That's a misnomer; they actually control the government of Lebanon. It means that Iran controls the government of Lebanon," Netanyahu said at a meeting with a delegation of foreign ambassadors to the UN.
It was the first time he publicly commented on the formation of the Lebanese government.
Netanyahu's statement comes after media reported on Saturday that the Iranian Armed Forces had successfully tested the country's new cruise missile with a range of over 1,350 kilometres (about 840 miles) on the occasion of celebrations marking the 40th anniversary of the 1979 Islamic Revolution.
Israel has been accusing Tehran of conducting a secret weapons program and trying to establish a military foothold in Syria, right on Israel's doorstep, with the Israeli armed forces carry out regular airstrikes against Iran's military targets in Syria.
