Iran's Islamic Revolutionary Guard Corps (IRGC) Navy claims to have intercepted a US underwater vehicle during a reconnaissance mission in the Strait of Hormuz, but the US military denied the Iranian claim shortly after.
In a statement, the IRGC Navy said it had seized the vessel following a "coordinated intelligence and electronic warfare operation". They further claim that the vehicle is a REMUS 600 and has been handed over to Iranian military experts "to retrieve its data".
