Iran's Islamic Revolutionary Guard Corps (IRGC) claimed responsibility for missile and drone strikes on a key US military base in Bahrain, escalating the regional conflict that began last week.

The strikes targeted the US Navy's Fifth Fleet headquarters in Juffair, Manama, according to IRGC statements. Iranian media reported that precision-guided solid- and liquid-fueled missiles hit the base on March 7, in retaliation for an alleged US attack on a desalination plant on Iran's Qeshm Island earlier that day. Earlier attacks occurred on February 28 and March 1, with the IRGC claiming to have destroyed a command building at the Sheikh Isa Air Base and damaged infrastructure at the Fifth Fleet facility.

Satellite imagery from Planet Labs confirmed visible damage at the Fifth Fleet naval base in Manama following the March 1 strikes, including structural impacts and smoke rising from the site. Photographs showed a building damaged by a drone attack in Juffair and fires at nearby facilities. Bahrain's defense ministry reported intercepting 54 drones and missiles since the conflict's onset, with air raid sirens activated multiple times.

No US military casualties have been confirmed at the Bahrain base. Bahrain reported one civilian killed and two injured from debris at Mina Salman Port on March 2, along with limited material damage in the Ma'ameer industrial area on March 5. Three people were injured in fresh aerial attacks reported early Sunday morning.

The attacks form part of Iran's broader retaliation after joint US-Israeli strikes on Iranian targets began on February 28. President Donald Trump described the US operation as aimed at regime change and curbing Iran's nuclear program. Iran has since launched waves of missiles and drones at US facilities across the Gulf, including in Qatar, Kuwait, and the UAE, as well as Israel.

Bahrain's US Embassy issued warnings for Americans to avoid certain Manama hotels housing personnel after initial strikes. The UK confirmed no casualties among its 300 troops near the base, and Canada reported none among its forces. Bahrain has bolstered its air defenses amid ongoing threats.

As of early Sunday, Gulf states including Bahrain continued to report interceptions of Iranian projectiles, with Kuwait noting strikes on a government building and fuel depot. The conflict has caused nearly 800 deaths in Iran and smaller numbers in Lebanon and Israel, according to officials.
