Feb. 19 (UPI) -- The United States has put military forces in place in the Middle East for a potential strike on Iran but President Donald Trump has not decided whether to attack or continue negotiations on Thursday.

A strike could occur as early as this weekend, with naval and air forces quickly coming into place. National security officials met in the Situation Room on Wednesday to discuss courses of action against Iran.

U.S. armed forces have been assembling in the Middle East in recent weeks as the United States and Iran have negotiated a scaling back of Iran's nuclear program. The latest conversations took place in Geneva on Tuesday, sans Trump who said he would be involved "indirectly."

The negotiations between the United States and Iran ended without a resolution on Tuesday. Trump has called for Iran to end its nuclear program.
