The Spanish and Dutch foreign ministers plan to arrive in Tehran on Tuesday night to hold talks with senior Iranian officials, including Iranian Foreign Minister Mohammad Javad Zarif, Qassemi said.
"Case 4,000 is most consistent of all cases, one with greatest explosive potential", he said, revealing scandal Hadasot news of second channel of Israeli television.
He stopped short of equating Iran with Nazi Germany but drew many comparisons.
"Iran also denies that it committed an act of aggression against Israel last week, that it sent a drone into our airspace to threaten our people".
Netanyahu claimed the part was from a drone which crossed into Israeli airspace, and was Iranian, and was shot down.
Analysts are sounding the alarm on Iran's expanding control of territory across war-torn Syria, stretching as far as the Mediterranean Sea, saying the country has exploited the chaos of the Syrian civil war and capitalised on the West's narrow focus on Islamic State.
Zarif later mocked Netanyahu's theatrics, calling it a "cartoonish circus".
"Israel will not allow Iran's regime to put a noose of terror around our neck", Netanyahu said during his speech.
"We are asking for your commitment that we should work together to seek a supplemental or follow-on agreement that addresses Iran's development or testing long-range missiles, ensures strong [International Atomic Energy Agency] inspections, and fixes the flaws of the 'sunset clause, ' " the cable said, according to Reuters.
Tehran says it wasn't Iran's drone. Moscow's help in curtailing Iran's growing influence in Syria, including its purported attempt to establish missile assembly sites there, is basic and irreplaceable.
Zarif suggested Netanyahu was deliberately raising tensions as a way to distract from his troubles at home.
"Fortunately today we are confronting with two opponents who are both grappling with domestic troubles; one of them with an economic corruption dossier and the other with election campaign offenses", said Mr. Rezaie referring to US President Donald Trump and Israeli PM Netanyahu.
The Iranian foreign minister also cited Israel's strikes against targets in Lebanon and its occupation of Palestinian lands.
In an interview with NBC News during the security conference, Mr Zarif said that Israel's loss of a fighter jet to Syrian anti-aircraft fire this month showed that its military had "crumbled". "We pray for peace, this is the Jewish culture, and we should do whatever we can to be there".
The foreign ministers of Iran, Russia and Turkey plan to meet in Kazakhstan in two weeks to prepare the ground for a summit due to be held in the Turkish city of Istanbul on Syria, the TASS news agency cited Zarif as saying on Monday.
