Kuwait halted all flights on Saturday after Iran launched one of its heaviest barrages of missiles and drones since the Middle East conflict began.

Kuwait Airways has rescheduled most of its flights due to the temporary suspension of takeoff and landing operations at Kuwait International Airport, the airline said on Saturday in a post on X. Iranian missile and drone attacks prompted the closure of the country’s airport, the airline said.

The Gulf state suffered one of its heaviest barrages since the Middle East conflict began. The latest Iranian attacks triggered multiple rounds of sirens from around dawn on Saturday, Bloomberg reported.

Iran struck two electricity and desalination facilities in Kuwait within 24 hours, Kuwait News Agency reported, citing the Ministry of Electricity, Water and Renewable Energy. The ministry said the attack prompted the precautionary shutdown of several generation units to protect workers and maintain the stability of the national electricity grid.

“Iran may have struck the Kuwaiti plant in response to recent US strikes on bridges in Iran and to deter the US from attacking Iranian energy infrastructure,” the Institute for the Study of War said.
