As nuclear talks between Iran and world powers advance toward a March 31 deadline, the Islamic regime announced Tuesday there is "90% agreement" regarding specifics of its nuclear program.

"There is agreement on 90% of technical issues," Iranian nuclear chief Ali Akbar Salehi said according to the Islamic Republic of Iran Broadcasting state media, reports Reuters.

Salehi, who spoke during negotiations in Switzerland's Lausanne, added "there is one very important issue that we still have differences about that in discussions this afternoon we will try to resolve."

The Iranian official's words somewhat contradict statements made by European officials, who said on Monday there is still a "long way to go" before reaching a permanent agreement building upon the interim agreement sealed in late 2013.

US Secretary of State John Kerry said on Saturday he hoped it would be possible to reach a deal with Iran "in the next days," if Tehran can show that its nuclear power program is for peaceful purposes only.

Israel has warned that the deal being formulated with Iran threatens Israel and the world at large, given that it leaves Iran with nuclear breakout capabilities that would allow it at the time of its choosing to breach the deal and produce a nuclear weapon in a short time span.

Iran has demanded to be allowed 190,000 centrifuges, an amount that would allow it to create a full nuclear arsenal within weeks.

Israeli Ambassador to the US Ron Dermer has noted there are 17 nations with peaceful nuclear programs in the world, and not a single one of them enriches uranium, putting the lie to Iran's insistence on having the capability so as to advance a "peaceful" program.

This week the Iranian parliament passed a proposal threatening to enrich uranium if the nuclear deal being formulated is breached, and in parallel the Islamic regime has developed a new advanced missile capable of reaching Israel, potentially with a nuclear payload.
