President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Despite a memorandum of understanding signed by both countries in June aimed at ending the war, talks broke down and the U.S. and Iran renewed strikes, with the strategic Strait of Hormuz as the primary flashpoint.
Across the region, fighting in Yemen between the Iranian-backed Houthis and Saudi-backed Yemeni forces has intensified in recent weeks and the militia group has also launched strikes on Saudi Arabia.
