Iranian oil tankers have begun traversing waters previously restricted by a US blockade, following a preliminary agreement between Iran and the United States aimed at de-escalating conflict. The agreement, signed remotely on Monday and slated for official ceremony in Switzerland on Friday, intends to end the war initiated by the US and Israel against Iran. While details are emerging, the current understanding is a starting point for further negotiations toward a comprehensive deal. Despite the agreement, Iran’s military has warned of a “severe response” to recent Israeli strikes in Lebanon. The lifting of the US port blockade allowed for the immediate passage of Iranian tankers. This development occurs against a backdrop of heightened regional instability and ongoing diplomatic efforts.
