(Reuters) - Russia successfully test-fired a hypersonic Zircon cruise missile over a distance of about 1,000 km (625 miles), the defence ministry said on Saturday.

       The missile was fired from the Barents Sea and hit a target in the White Sea, it said. Video released by the ministry showed the missile being fired from a ship and blazing into the sky on a steep trajectory.

       President Vladimir Putin has described the Zircon as part of a new generation of unrivalled arms systems. Hypersonic weapons can travel at nine times the speed of sound, and Russia has conducted previous test-launches of the Zircon from warships and submarines in the past year.

       Russia's military has suffered heavy losses of men and equipment during its three-month invasion of Ukraine, which it calls a "special operation", but it has continued to stage high-profile weapons tests to remind the world of its prowess in missile technology.

       Last month it test-launched a new nuclear-capable intercontinental missile, the Sarmat, capable of carrying 10 or more warheads and striking the United States.
