WASHINGTON, April 19 -- Iranian forces launched drone strikes yesterday on multiple American vessels in retaliation for US forces firing on and intercepting an Iranian ship, Anadolu Ajansi reported, citing local media.

The semi-official news agency Tasnim reported that after US forces boarded the container ship Touska in the Gulf of Oman, Iranian drones were launched against American vessels, without specifying whether the targets were military or commercial.

Iran had confirmed earlier that US forces seized the Iranian vessel and warned that it would retaliate "soon" following the move, which it called a violation of a Pakistan-brokered two-week ceasefire that has largely held since it was announced on April 7.
