DUBAI, United Arab Emirates (AP) — Iran has fired more drones and missiles at Israel and Gulf Arab countries as it keeps up pressure on the Middle East in a war that has sent oil prices surging and stunned global economies. The Saudi Defense Ministry said on Tuesday that it has destroyed two drones over the kingdom’s oil-rich eastern region, while in Kuwait, the National Guard said it shot down six drones attacking the county’s northern and southern areas. The attacks come as U.S. President Donald Trump sends contradictory signals about how long the war could last, adding to uncertainty that’s causing markets to swing.
