Brent briefly fell over $1 a barrel.

"It depends on ‌whether ⁠or not they sign a very strong agreement," Trump told CNN in a phone interview. "The answer is, highly unlikely ​it's going ​to ⁠be necessary."

Trump had hinted at renewing major attacks on ​Iran after last week's US ​midterm ⁠elections, but there has been no sign of a large-scale US military operation. ⁠Iran ​has said it ​would respond by striking US and Israeli targets.
