Iranian President Hassan Rouhani says he will present a regional security plan dubbed the “Hormuz Peace Endeavour” during the U.N. General Assembly this week, as he called on foreign powers to leave the Persian Gulf amid escalating tensions between the U.S. and Iran.

On Friday, the Trump administration said it would deploy military forces to Saudi Arabia, as well as impose new sanctions on Iran’s Central Bank and other financial institutions. The announcements from D.C. were in response to last weekend’s drone attacks on Saudi oil facilities, which the U.S. has blamed on Iran. Iran has denied any involvement in the attack, which was claimed by Yemen’s Houthi movement.

In more news about Iran, a government spokesperson said today that the British-flagged Stena Impero oil tanker, which was seized in the Strait of Hormuz in July, was free to leave.
