U.S. President Donald Trump warned Friday that limited strikes on Iran remain an option, even as Tehran’s top diplomat said a draft agreement could be ready within days after renewed nuclear talks with Washington.

In response to a reporter's question on whether the U.S. could take limited military action as the countries negotiate, Trump said, "I guess I can say I am considering that.” A few hours later, he told reporters that Iran "better negotiate a fair deal.”

Iranian Foreign Minister Abbas Araghchi said in a TV interview earlier that his country was planning to finalize a draft deal in "the next two to three days” to send it to Washington.

"I don’t think it takes long, perhaps, in a matter of a week or so, we can start real, serious negotiations on the text and come to a conclusion,” Araghchi said on MSNOW's "Morning Joe” show.

The tensions between the longtime adversaries have ramped up as the Trump administration pushes for concessions from Iran and has built up the largest U.S. military presence in the Middle East in decades, with more warships and aircraft on the way. Both countries have signaled that they are prepared for war if talks on Tehran’s nuclear program fizzle out.
