Iran fired missiles at Kuwait and Bahrain in the early hours of Wednesday, and the United States launched strikes on Iran’s Qeshm Island, as tensions in the Gulf spiked amid an impasse in diplomatic efforts to end the war between Tehran and Washington that is now closing in on 100 days.Since the conflict began in late February, Iran has repeatedly targeted countries across the Gulf where US military bases are located. Armed hostilities had largely subsided after a temporary Pakistan-mediated ceasefire took effect on April 8. But the latest flare‑up has raised fears that full‑scale fighting could resume.Here is a look at what happened overnight, and where things stand on the diplomatic front.What happened in Kuwait and Bahrain?Kuwait’s state news agency KUNA said Iranian missiles and drones had hit the country’s international airport on Wednesday morning. It reported an unspecified number of injuries, damage to airport facilities and flight suspensions and diversions.India’s foreign ministry condemned the attack on the Kuwait International Airport. In a statement released on Wednesday, the ministry said that an Indian national has been killed and “several of our nationals are injured”.“We offer our deepest condolences to the bereaved family. Our Embassy is extending all possible assistance to those injured. We remain in close contact with local authorities for the welfare of Indian nationals,” it said.But US Central Command (CENTCOM) said two Iranian missiles shot at Kuwait fell short or broke apart in flight, while several ballistic missiles failed to reach their targets. Iran’s semi-official Tasnim news agency earlier said the Islamic Revolutionary Guard Corps (IRGC) had launched missiles and drones at US helicopters stationed in a regional country, in an apparent reference to Kuwait.It is unclear whether the US helicopters the IRGC was reportedly targeting were stationed at the Kuwaiti airport or whether intercepted projectiles fell by accident on the airport.According to Tasnim, the IRGC also fired missiles and drones at an airbase and the headquarters of the US Fifth Fleet in Bahrain, where sirens went off warning residents of an attack.However, CENTCOM said it had intercepted the projectiles aimed at Bahrain. It also said no US personnel or assets were harmed in the attacks on Kuwait and Bahrain.Was Iran also hit?Just before Iran fired missiles and drones at Kuwait and Bahrain, US forces hit a telecommunications tower on Iran’s Qeshm Island, which sits in the Gulf and is believed to be a repository of the country’s missiles stored in underground facilities.CENTCOM said the US military also downed Iranian drones targeting civilian ships in regional waters.Tehran said US forces struck an Iranian oil tanker near the Strait of Hormuz, damaging its engine room. Iranian media reported the IRGC’s navy targeted a vessel it identified as “Panaya” with missiles in response to the attack on the Iranian tanker.Hold on, so who hit whom first?The US and Iran have competing narratives. But the Trump administration has made clear that it will not allow Iranian oil to pass through the Strait of Hormuz as it maintains its blockade of Iranian ports and ships.
