U.S. President Donald Trump has said he was deciding whether to "make a deal" with Iran or "finish it off" as investors weigh heightened tensions across the Middle East.
"Do I finish it off, which would be very easy to do, or do I make a deal? It's getting to be decision time," Trump said in a Fox News interview on Sunday.
Mediators from Qatar, which has played a key role in efforts to negotiate an agreement between Washington and Tehran, visited Tehran on Sunday, per Reuters. It comes as attacks by Iran-backed Houthi militants on Saudi Arabia continued over the weekend.
The last confirmed U.S. strikes on Iran were on Sept. 1. Trump previously said strikes would not resume until after the Nov. 3 midterm elections. Tehran says it is preparing a military response to any U.S. attacks.
A potential U.S. target could be Pickaxe Mountain, a deeply buried site linked to Iran's nuclear program, Trump said in the Sunday interview.
