UK says Iranian vessels tried to block ship

Teheran dismisses British claim as 'worthless' and 'made to create tension'

DUBAI, United Arab Emirates - The British navy said it prevented three Iranian paramilitary vessels from impeding the passage of a British commercial ship in the Strait of Hormuz early on Thursday, a day after Teheran warned of repercussions for the seizure of its own supertanker.

But Iran's Revolutionary Guard denied the allegations, saying if it had received orders to seize any ships, it would have done so immediately.
