Trump said Iran needs to stop pursuing nuclear weapons, and warned of possible future action if it did not cease such efforts.

Axar.az reports “So we’re going to find out where they are now about what they’re going to do with nuclear. They can’t do the nuclear,” Trump said in his CNBC interview Wednesday at the World Economic Forum.

“They gotta stop with the nuclear.”

Trump also said that Iran had ceased killing protestors after he warned the nation last week of possible military action.

“They were gonna hang 837 people on Thursday,” he said. “I told them, ‘You can’t do that.’”

“We hope there’s not going to be further action,” Trump said. “They were shooting people indiscriminately on the streets.”
