(Associated Press) The U.S. military released a video Friday it said showed Iran’s Revolutionary Guard removing an unexploded limpet mine from one of the oil tankers targeted near the strategic Strait of Hormuz, suggesting Tehran wanted to hide evidence of its alleged involvement.

Iran denied any role in Thursday’s apparent attacks, which have again roiled the Persian Gulf amid heightened tensions between Tehran and Washington over the unraveling nuclear deal with world powers.

Four other oil tankers off the nearby Emirati port city of Fujairah suffered similar attacks in recent weeks, and Iranian-allied rebels from Yemen have struck U.S. ally Saudi Arabia with drones and missiles.
