US President Donald Trump says Iran must immediately stop its financial and military support for "terrorists and militas" and he reiterated that it never be permitted to possess atomic arms.
"Most importantly, the United States and Israel can declare with one voice that Iran must never be allowed to possess a nuclear weapon - never, ever - and must cease its deadly funding, training and equipping of terrorists and militias, and it must cease immediately," Trump said in public remarks at a meeting in Jerusalem with Israeli President Reuven Rivlin.
Trump stressed the common threat Iran presents to Israel and its neighbouring Arab countries, as well as the dangers of Tehran possessing a nuclear weapon, after meeting with Israeli President Reuven Rivlin on Monday.
"There is growing realisation among your Arab neighbours of the commonality of the threat emanating from Iran," said Trump at the Israeli president's Jerusalem residence.
"Iran must never be allowed to possess a nuclear weapon - never ever," Trump added.
Rivlin, who also called for keeping Iran "out of our borders," thanked Trump for US actions in Syria, saying there were "red lines that must never be crossed," in reference to US missile strikes in retaliation for a presumed chemical attack on Syrian civilians last month.
Earlier Iran accused the US of selling arms to "dangerous terrorists" in the Middle East and of spreading "Iranophobia".
"Once again, by his repetitive and baseless claims about Iran, the American president ... tried to encourage the countries of the region to purchase more arms by spreading Iranophobia," Foreign Ministry spokesman Bahram Qassemi trold state TV, a day after Trump ended a visit to Tehran's arch-foe Saudi Arabia where arms deals worth almost $US110 billion ($A148 billion) were signed.
