"Either we reach an agreement or it's going to be bad for them," Trump told reporters on his presidential plane.
When asked how much time Iran would be given, Trump replied:
10–15 days, max.
Earlier on Thursday, the US president said that the world will probably see how things go in the next ten days.
"We have to reach a meaningful agreement or bad things will happen," Trump said during the first meeting of the so-called "peace council."
The US and Iran held indirect talks in Geneva earlier this week. US Secretary of State Marco Rubio is expected to hold talks with Israeli Prime Minister Benjamin Netanyahu in Israel on February 28.
