Iran has launched multiple waves of missile attacks targeting U.S. military bases across the Middle East, including bases in Kuwait, the UAE, Qatar, and Bahrain, Iran's state media reported on Saturday.

Iranian Foreign Minister Abbas Araghchi said that all U.S. military bases in the region are now considered legitimate targets of Iran's military.

In Bahrain, a missile attack hit a service center belonging to the U.S. Fifth Fleet, Bahrain's National Communication Centre said.

Blasts were also heard over central Doha and near the Al-Udeid military base -- the largest U.S. military facility in the region, according to media reports.

U.S. President Donald Trump said early Saturday that the U.S. forces are carrying out a "massive and ongoing" attack on Iran to "destroy their missiles and raze their missile industry to the ground."
