Two large oil tankers, including a sanctioned vessel carrying Russian crude, caught fire after colliding near the Strait of Hormuz, raising concerns among global oil traders and shipping operators.
Security analysts say Russia is operating hundreds of vessels to get around the sanctions imposed on its oil exports over its 2022 invasion of Ukraine.
A number of people abandoned the vessels after the crash in the North Sea, with the RNLI sending rescue boats from Bridlington and several seaside towns in Lincolnshire.
