In a significant move, the U.S. State and Treasury Departments have jointly announced sanctions against four individuals from Bahrain allegedly involved with the Iran-backed militant group, Al-Ashtar Brigades (AAB). This development marks a notable shift in the Biden administration's stance toward Iran, moving away from a conciliatory approach initiated in January 2021.

Al-Ashtar Brigades, identified as a Bahraini Shia militant group, has been implicated in planning and executing terrorist attacks against the Bahraini government with the assistance of Iran, according to the Office of the Director of National Intelligence (ODNI).

The AAB, which split from the 14 February Youth Coalition in 2013, has claimed responsibility for approximately 20 attacks primarily targeting local police and security forces in Bahrain. The ODNI also highlights the Iranian Islamic Revolutionary Guard Corps (IRGC) providing weapons and training to the group, with Bahraini security forces intercepting shipments from Iran containing explosively formed penetrators destined for the AAB.

Moreover, the AAB has forged alliances with Iranian-backed Iraqi Shia militants and Lebanese Hezbollah, receiving financial and logistical support from these groups.

This latest round of U.S. designations targets individuals directly linked to the AAB's operations, all of whom are based in Iran. Hussein Ahmad Al-Dammami, convicted in Bahrain for various crimes including attempted murder and terrorism, fled to Iran following sentencing and asset seizures. Ali Abdulnabi Alshofa, Hasan Ahmed Radhi Sarhan, and Isa Saleh Salman are also designated for their alleged roles in facilitating lethal aid and plotting terrorist operations for the AAB.

State Department Spokesperson Matthew Miller emphasized the U.S. government's commitment to countering destabilizing forces emanating from Iran, particularly those posing threats to regional partners. The sanctions underscore Washington's determination to target individuals and entities supporting terrorist activities in the region.

This move is likely to further strain relations between the United States and Iran, as tensions persist over various regional issues, including Iran's alleged support for proxy groups and its nuclear program.

The announcement comes amid mounting pressure on the Biden administration to take a tougher stance against Iran, with concerns raised by lawmakers regarding the lack of direct action against Iranian entities facilitating attacks on international shipping, particularly in Yemen.
