British tanker's owners say unable to contact vessel after "attack" in Strait of Hormuz

The Swedish owner of the UK-flagged tanker Stena Impero, which the Iranian Revolutionary Guard said Friday had been confiscated in the Strait of Hormuz, said the ship had been "attacked" and was heading towards Iran.

Stena Bulk and Northern Marine Management said in a statement that it "can confirm that... our managed vessel Stena Impero was attacked by unidentified small crafts and a helicopter while transiting the Strait of Hormuz while the vessel was in international waters."
