The United States and Iran announced a deal Sunday to formally end their ongoing conflict, including a cessation of the U.S. blockade against Iran. A key component of the agreement involves reopening the strategically vital Strait of Hormuz, potentially easing global energy prices by allowing resumed oil shipments. The deal’s announcement prompted immediate reactions from international leaders. Britain, France, Germany, and Italy jointly emphasized the importance of preventing Iran from developing nuclear weapons, expressing willingness to collaborate with the U.S., Iran, and the International Atomic Energy Agency (IAEA) to achieve this goal. British Prime Minister Keir Starmer also responded to the news, though his statement was not included in the provided text. The agreement marks a significant shift in relations between the two nations after years of tension.
