The eight-member International Maritime Security Construct (IMSC) is still operating in the Middle East Gulf.

The coalition, spearheaded by the US in response to a series of tanker attacks in 2019, held exercises in the waterway on Wednesday with a Bahrain navy ship and two US Coast Guard vessels conducting communication drills and tactical manoeuvres.

“Deterring state-based threats to maritime trade whilst also reassuring the commercial shipping industry remains the core mission of IMSC,” said UK Royal Navy commodore Don Mackinnon, the IMSC's commander.
