Kuwait briefly shut its main airport Wednesday after Iranian drones heavily damaged a passenger terminal building, killed one person and wounded dozens — the latest in back-and-forth attacks by Tehran and Washington that test a fragile ceasefire.

The strike again brought home the risks to residents and travellers in Gulf countries that had considered themselves relative havens before the war, now in its fourth month.

Talks have dragged on for weeks as mediators seek a more enduring truce in the US-Israeli war with Iran. Now they are further strained by Israel’s broadening war with the Iranian-backed Hezbollah in Lebanon.

A regional official said Iran wanted a separate ceasefire in Lebanon enforced before returning to talks. US President Donald Trump asserted that negotiations continued.

Iran maintains its hold on the Strait of Hormuz — a crucial waterway for the world’s oil and natural gas and related products like fertilizer — and the US continues its blockade of Iranian ports. Global fuel prices remain high, and the effects of the conflict are felt well beyond the region.
