A wave of drone attacks struck multiple countries across the region Thursday night, with explosions reported in Dubai and strikes targeting infrastructure in Kuwait and Saudi Arabia.

According to reports from the Iraqi “Sabereen” channel, which is affiliated with pro-Iranian militias, explosions in Dubai were the result of a drone attack on U.S. targets in the United Arab Emirates. At the same time, there were reports that air defense systems were activated in several locations inside Iran.

Kuwait also confirmed that it was under drone attack, stating that its air defense systems had been deployed. While authorities have not officially blamed any party, Iran has carried out multiple attacks on Kuwait during the course of the war.

In a statement, the Kuwaiti military said: “Air defense systems are dealing with hostile drone attacks that penetrated the country’s airspace and struck several vital infrastructures.”

Meanwhile, a Saudi Energy Ministry official told the kingdom’s state news agency that a number of oil and gas facilities, refineries, petrochemical plants, and power stations were targeted in repeated attacks attributed to Iran. The strikes hit areas around the capital Riyadh, eastern regions of the country, and the port city of Yanbu on the Red Sea.

The official also confirmed that an oil pipeline connecting production fields to the port of Yanbu was struck, resulting in a loss of approximately 700,000 barrels of exports per day. In addition, two oil wells were damaged, reducing output by about 600,000 barrels per day.
