Amid Ukraine war, Russia test-fires its latest hypersonic Zircon missile, hits target 1,000 km away

MOSCOW: The Russian navy on Saturday conducted another test of a prospective hypersonic missile, a demonstration of the military's long-range strike capability amid the fighting in Ukraine.

The Defense Ministry said the Admiral Gorshkov frigate of the Northern Fleet in the White Sea launched the Zircon cruise missile in the Barents Sea, successfully hitting a practice target in the White Sea about 1,000 km (540 nautical miles) away.

The launch was the latest in a series of tests of Zircon, which is set to enter service later this year.

Russian President Vladimir Putin has said that Zircon is capable of flying at nine times the speed of sound and has a range of 1,000 km (620 miles).

Putin has emphasized that its deployment will significantly boost the capability of Russia's military.

Zircon is intended to arm Russian cruisers, frigates and submarines and could be used against both enemy ships and ground targets.

It is one of several hypersonic missiles under development in Russia.

Russian officials have boasted about Zircon's capability, saying that it's impossible to intercept with existing anti-missile systems.

Putin, who has sternly warned Western allies against interfering in Ukraine, has warned in the past that Russian warships armed with Zircon would give Russia a capability to strike "decision-making centres" within minutes if deployed in neutral waters.

Russia asserted Saturday that its troops and separatist fighters had captured a key railway junction in eastern Ukraine, the second small city to fall to Moscow's forces this week as they fought to seize all of the country's contested Donbas region.

Russian Defense Ministry spokesman Igor Konashenkov said the city of Lyman had been "completely liberated" by a joint force of Russian soldiers and the Kremlin-backed separatists, who have waged war in the eastern region bordering Russia for eight years.

Lyman, which had a population of about 20,000 before Russia invaded Ukraine on Feb.24, serves as a regional railway hub.

Ukraine's train system has ferried arms and evacuated citizens during the war, and it wasn't immediately clear how the development might affect either capability.

Controlling the city would give the Russian military a foothold for advancing on larger Ukrainian-held cities in Donetsk and Luhansk, the two provinces that make up the Donbas.

Since failing to occupy Kyiv, Ukraine's capital, Russia has concentrated on seizing the last parts of the region not controlled by the separatists.

"If Russia did succeed in taking over these areas, it would highly likely be seen by the Kremlin as a substantive political achievement and be portrayed to the Russian people as justifying the invasion," the British Ministry of Defense said in a Saturday assessment.

Fighting continued Saturday around Sievierodonetsk and nearby Lysychansk, twin cites that are last major areas under Ukrainian control in Luhansk province.

Ukrainian President Volodymyr Zelenskyy reiterated that the situation in the east was "difficult" but expressed confidence his country would prevail.

"If the occupiers think that Lyman or Sievierodonetsk will be theirs, they are wrong. Donbas will be Ukrainian," he said.

On Tuesday, Russian troops took over Svitlodarsk, a small municipality south of Sievierodonetsk that hosts a thermal power station, while intensifying efforts to encircle and capture the larger city.

The governor of Luhansk warned that Ukrainian soldiers might have to retreat from Sievierodonetsk to avoid being surrounded.

The advance of Russian forces raised fears that residents would experience the same horrors as people in the southeastern port city Mariupol in the weeks before it fell.

Sievierodonetsk's mayor, Oleksandr Striuk, said Friday that some 1,500 civilians have died there during the war, including from a lack of medicine or because of diseases that could not be treated while the city was under siege.

Before the war, Sievierodonetsk was home to around 100,000 people.

About 12,000 to 13,000 remain in the city, where 90% of the buildings are damaged, the mayor told The Associated Press.

Ukraine's police force said Saturday afternoon that the city is "under constant enemy fire" and civilians were wounded, but did not specify the number.

Just south of Sievierodonetsk, volunteers worked to evacuate people Friday amid a threatening soundtrack of air raid sirens and booming artillery.

AP reporters saw elderly and ill civilians bundled into soft stretchers and slowly carried down apartment building stairs in Bakhmut, a city in northeast Donetsk province.

Svetlana Lvova, the manager of two buildings in Bakhmut, tried to convince reluctant residents to leave but said she and her husband would not evacuate until their son, who was in Sieverodonetsk, returned home.

"I have to know he is alive. That's why I'm staying here," Lvova, 66, said.

A nearly three-month siege of Mariupol ended last week when Russia claimed the city's complete.

The city became a symbol of mass destruction and human suffering, as well as of Ukrainian determination to defend the country.

More than 20,000 of its civilians are feared dead.

Mariupol's port reportedly resumed operations after Russian forces finished clearing mines in the Azov Sea off the once-vibrant city.

Russian state news agency Tass reported that a vessel bound for the southern Russian city of Rostov-on-Don entered Mariupol's seaport early Saturday.

Meanwhile, the Ukrainian navy said Saturday morning that Russian ships "continue to block civilian navigation in the waters of the Black and Azov seas" along Ukraine's southern coast, "making them a zone of hostilities."

The war in Ukraine has caused global food shortages because the country is a major exporter of grain and other commodities.

Moscow and Kyiv have traded blame over which is responsible for keeping shipments tied up, with Russia saying Ukrainian sea mines prevented safe passage.

The press service of the Ukrainian Naval Forces said in a Facebook post that two Russian missile carriers "capable of carrying up to 16 missiles" were ready for action in the Black Sea.

It said that only shipping routes which had been established through multilateral treaties could be considered safe.

Ukrainian officials pressed Western nations for more sophisticated and powerful weapons, especially multiple launch rocket systems.

The U.S. Defense Department would not confirm a Friday CNN report saying the Biden administration was preparing to send long-range rocket systems to Ukraine.

Russian Foreign Minister Sergei Lavrov warned that providing rockets that could reach his country would represent "a most serious step toward unacceptable escalation."

He spoke in an interview with RT Arabic that aired Friday.

In Russia on Saturday, President Vladimir Putin signed into law a bill that raises the age limits for Russian army contracts.

Contractors can now first enter service until age 50 and work until they reach legal retirement age, which is 65 for men and 60 for women.

Previously, Russian law set an age limit of 40 for Russians and 30 for foreigners to sign an initial contract.

Russia's Defense Ministry said the Russian navy successfully launched a new hypersonic missile from the Barents Sea.

The ministry said the recently developed Zircon hypersonic cruise missile had struck its target about 1,000 kilometers away.

If confirmed, the launch could spell trouble for NATO voyages in the Arctic and North Atlantic.

Zircon, described as the world's fastest non-ballistic missile, can be armed with either a conventional or a nuclear warhead and is said to be impossible to stop with current anti-missile defense systems.

Moscow's claims, which could not be immediately verified, came a week after Defense Minister Sergey Shoigu announced that Russia would form new military units in the west of the country in response to Sweden and Finland's bids to join NATO.

Putin marked the annual Border Guards Day by congratulating the members of the Russian service.

"The tasks you are facing are particularly important now, given the unprecedented political, economic and information pressure on our country and the buildup of NATO military capacity right at Russia's borders," Putin said.
