DUBAI, United Arab Emirates (AP) — Israel and Iran exchanged fire early Wednesday, with Tehran keeping up pressure on the region’s oil industry, targeting infrastructure and ships as global energy concerns mounted and the war in the Middle East showed no signs of abating.

Two Iranian drones hit near Dubai International Airport, home to the long-haul carrier Emirates, and the world’s busiest for international travel. Four people were wounded but flights continued, the Dubai Media Office said.

Early Wednesday, a projectile hit a container ship off the coast of Oman in the Strait of Hormuz, setting it ablaze and forcing the crew to abandon the vessel, the British military said. Kuwait said its defenses downed eight Iranian drones and Saudi Arabia said it intercepted five drones heading toward the kingdom’s Shaybah oil field.

Iran has effectively stopped cargo traffic in the narrow strait through which about a fifth of all oil is shipped from the Persian Gulf toward the Indian Ocean. It has also targeted oil fields and refineries in Gulf Arab nations, aiming at generating enough global economic pain to pressure the United States and Israel to end their strikes.

The U.N. Security Council was to vote later Wednesday on a resolution sponsored by the Gulf Cooperation Council demanding Iran stop attacking its Arab neighbors.
