Nuclear talks with Iran must continue, President Donald Trump on Wednesday told Israeli Prime Minister Benjamin Netanyahu in a meeting at the White House, rebuffing the Israeli prime minister's push for a tougher stance against Tehran.

"There was nothing definitive reached other than I insisted that negotiations with Iran continue to see whether or not a Deal can be consummated," Trump said on social media after their three-hour meeting.

"If it can, I let the Prime Minister know that will be a preference. If it cannot, we will just have to see what the outcome will be," said Trump, adding a reminder of last year's U.S. strikes against Iran's nuclear program.

Seeking to push for the Iran’s ballistic missile program to be included in any deal, Netanyahu had rushed to Washington for his seventh meeting with Trump since the U.S. leader returned to power.

Netanyahu's office said that during the talks with Trump the Israeli premier had "insisted on the security needs of the state of Israel in relation to the negotiations" on Iran.
