July 27 (UPI) -- President Donald Trump said Monday that the United States paused attacks on Iran at Iranian leaders' request but said he would order "strong military action" if negotiations fail.

However, there were mixed messages on what those talks entailed Monday. Iran's Foreign Ministry said there were no new negotiations with the United States, CNN reported, though there are discussions with Oman over the Strait of Hormuz.

The United States halted attacks on Iran three days ago after 13 consecutive days of nightly bombing.

"We are in very deep talks with Iran," Trump told Axios during an interview Monday. "If they don't work out, we will go back to very strong military action."
