Iran US Conflict

"We are hopeful that the United States does not make this strategic mistake," foreign ministry spokesman Bahram Qasemi was quoted as saying.

This was the latest signal that Trump, who campaigned against the deal and at times suggested he would scrap it, has as president adopted a more toned-down posture related to the Iranian regime.

A spokesman from the Iranian Foreign Ministry said that the country's most recent missile launch was not meant as a message to the Trump administration.

The aim of the military exercise in Semnan province was to "showcase the power of Iran's revolution and to dismiss the sanctions."

"The Trump Administration condemns such actions by Iran that undermine security, prosperity, and stability throughout and beyond the Middle East and place American lives at risk."

The Iranian vessels came within 800 meters of the Mahan, which was escorting two other US military ships near the Strait of Hormuz.

Rear Admiral Ali Fadavi: "This ship increases the deterrent power of Iran and will have an effect on the calculations of the enemy, particularly America."

"In regards to security, I am more extreme than Netanyahu," Herzog remarked.
