A US Navy warship seized weapons believed to be of Iranian "design and manufacture" aboard an Iranian traditional sailing vessel, the American military said on Thursday.
In a statement, the military said the guided-missile cruiser Normandy boarded the dhow in the Arabian Sea on Sunday.
"The weapons seized include 150 'Dehlavieh' anti-tank guided missiles (ATGM), which are Iranian-manufactured copies of Russian Kornet ATGMs," the statement said.
"Other weapons components seized aboard the dhow were of Iranian design and manufacture and included three Iranian surface-to-air missiles," it said.
The military said that the weapons seized on Sunday were "identical" to those seized by another US warship in November.
Last year, the guided-missile destroyer Forrest Sherman seized advanced missile parts - believed to be linked to Iran and aimed for delivery to Yemen’s Houthis militias - from a boat it had stopped in the Arabian Sea.
In recent years, US warships have intercepted and seized Iranian arms bound for the Houthis.
Under a United Nations resolution, Tehran is prohibited from supplying, selling or transferring weapons outside the country.
A separate UN resolution on Yemen bans the supply of weapons to Houthi leaders.
