Iran has published a list of major bridges across the Persian Gulf region it said could come under “tit-for-tat” retaliation, following the U.S.-Israeli coalition’s strike on the B1 bridge earlier in the day. Iran’s targets include bridges in Kuwait, the United Arab Emirates, Jordan, and the King Fahd Causeway linking Saudi Arabia to the island nation of Bahrain.

Iran’s threat of escalation came as it announced a wave of drone and missile attacks on Gulf nations, including U.S.-owned steel plants in the UAE and a weapons factory in Israel. Iran said one attack targeted a data center of the U.S. software company Oracle in Dubai; UAE officials denied the claim. Iran also said it struck an Amazon cloud computing center in Bahrain.

Meanwhile, Kuwait said Iran struck a power and desalination plant earlier today, hours after it struck an oil refinery, sparking a number of fires.
Separately, Yemen’s Houthis said they’d fired a barrage of ballistic missiles at Israel, in coordination with Iran and Hezbollah in Lebanon.

In Iraq, an Iranian-backed militia claimed responsibility for six attacks on U.S. military bases over a 24-hour period. The attacks came as two Iranian drones struck a U.S. diplomatic support facility at Baghdad International Airport on Thursday evening.
