Iranian Foreign Minister Mohammad Javad Zarif, who also addressed the conference, called Netanyahu's presentation "a cartoonish circus". The channel says two people arrested are Netanyahu associates and that Netanyahu, who held the communications portfolio until a year ago, is expected to be questioned.
In Munich, where 11 Israeli athletes were killed by Islamic terrorists in 1972, Netanyahu suggested the Obama administration's 2015 nuclear deal with Iran was like the 1938 Munich Pact that appeased the Nazis and led to World War II.
At the same time, Syria appears to feel it now has the upper hand in the civil war and is more emboldened to stop Israeli air raids inside the country, analysts say. Their inaction "made a wider war inevitable and far more costly", he said.
"Israel will not allow Iran's regime to put a noose of terror around our neck", he asserted.
"There is special meaning to the fact that we are standing at the place where 11 of our athletes were murdered just because they were Jews and Israelis", Netanyahu said.
"He claims Iran is fighting extremism, and he argues the conflict in the Middle East won't be resolved by a military solution", Netanyahu said.
During the attack, multiple anti-aircraft missiles were fired at IAF aircraft.
During the strikes, one of Israel's F-16 fighter jets was shot down, believed to be the first loss of an Israeli plane in combat since 1982. The pilots ejected over Israel and one was seriously injured.
"The Syrians and the Iranians, from our point of view, are playing with fire".
Those held were being questioned over whether they were involved in illegal dealings between the Israeli prime minister and the owner of Israel's largest telecommunications firm. John Kerry, the former U.S. secretary of state who helped clinch the deal, said it was "absolutely critical" to ensure it survived. "However, we are not looking to escalate the situation", stated IDF spokesman Lt. Col. Jonathan Conricus.
