Iranian President Hassan Rouhani called Thursday for Israel to put its suspected nuclear arms under international control ahead of a landmark meeting between foreign ministers from Iran and Western nations.
Rouhani also said he believed a deal could be made on his country's nuclear drive within three to six months.
Rouhani spoke at a UN nuclear disarmament conference ahead of a meeting between Iran's Foreign Minister Javad Mohammad Zarif and US Secretary of State John Kerry and ministers from Britain, China, France, Germany and Russia.
The meeting will be held to discuss Western accusations that Iran is seeking a nuclear bomb capability. It will also be one of the highest level Iran-US encounters since 1979.
At the UN conference, Rouhani said Israel should join the Non-Proliferation Treaty, which aims to contain the spread of nuclear weapons. Israel has never declared having a nuclear bomb but is widely suspected to have several.
Rouhani noted the failed attempts to organize a Middle East nuclear free zone. "Israel, the only non-party to the Non-Proliferation Treaty in this region, should join without any further delay."
He said that "all nuclear activities in the region" would then be subject to International Atomic Energy Agency safeguards.
"No nation should possess nuclear weapons, since there are no right hands for these wrong weapons," Rouhani said.
Rouhani told the Washington Post he wants a quick accord to end Western accusations that Iran is seeking a nuclear bomb. He said he has the full backing of Iran's supreme leader Ayatollah Ali Khamenei to broker a deal.
"The only way forward is for a timeline to be inserted into the negotiations that's short - and wrap it up," said Rouhani. "If it's three months, that would be Iran's choice, if it's six months, that's still good. It's a question of months not years."
