US President Donald Trump has said that Washington still has “one or two” targets to "take care of" in Iran.

Axar.az reports, citing CBS News, that Trump made the remarks on Saturday while speaking to reporters at his residence in Florida.

“We've knocked out their nuclear. We still have to take care of, I would say, one or two sites, but we can do that in 10 minutes,” Trump said.

He specifically referred to the suspected underground nuclear complex at Pickaxe Mountain, saying: “You probably could look at Pickaxe Mountain, and you have to take care of that. We can do that all very quickly.”

The Iranian government has denied that any nuclear activities are being conducted at the site.

Trump also said negotiations with Tehran to end the war, which was launched by the United States and Israel in February, were “going fine”, but added that “they're not very reliable”.
