Talks between the U.S. and Iran have stalled despite the two countries signing a memorandum of understanding in June, aimed at ending the war.
The two sides have since exchanged strikes. The U.S. says it is enforcing a blockade preventing any Iranian ships from entering or leaving the country, while Iran claims the Strait of Hormuz remains closed.
The U.S. also continues to accuse Iran of targeting commercial shipping in the Strait of Hormuz, a flashpoint in the war.
Meanwhile, the Iranian-backed Houthis repeatedly attacked Saudi Arabian military and oil infrastructure facilities. This lead to intensified fighting in Yemen between the Houthis and Saudi-backed Yemeni forces. Saudi Arabia has also gathered an international coalition to fight off the Houthis.
