Vladimir Putin, the Russian president, has accused Ukraine of carrying out a attack on one of its liquefied natural gas (LNG) carriers, which exploded and sank into the Mediterranean Sea off Libya. Explosions were reported on the Arctic Metagaz, which had been carrying 61,000 tonnes of LNG, on Tuesday night when the ship was about 150 miles (240km) off the coast of Libya.

Russia’s transport ministry had claimed that the Arctic Metagaz had been hit by Ukrainian drones launched from the Libyan coast.
