Bombay Durpun - Russia says Ukraine using long-range US artillery

The statement from Russia's defence ministry came a day after Ukraine said it received modern Leopard and Challenger battle tanks from Germany and the United Kingdom to push back Moscow's army in east and southern Ukraine.

Fighting in recent months between Russian and Ukrainian forces has concentrated on the eastern city Bakhmut, and Kyiv says it is holding out in the Donetsk region urban hub to exhaust Russian forces and then more easily push them back.

"Air defence (forces) downed... a GLSDB guided rocket," Russia's defence ministry said in a statement, referring to ground-launched small diameter bombs produced by Boeing and the Saab Group.

These devices have a range of up to 150 kilometres (93 miles), which would threaten Russian positions and supply depots far behind the front lines.

The Pentagon announced last month it was providing Ukraine with the artillery as part of a $2.2 billion arms package.

"This gives them a longer-range capability... that will enable them to conduct operations in defence of their country and to take back their sovereign territory," Pentagon spokesman Pat Ryder said at the time.

Ukraine had been asking the United States for munitions that can fly farther than the HIMARS rockets, which have an 80-kilometre range.

The West had been wary of supplying the weapons over concerns Kyiv could use them to target Russia.

HIMARS played an important role in Ukraine's recapture of Kherson in the south last year but the GLSDB potentially gives Ukraine forces an ability to strike anywhere in the Russian-held parts of Ukraine.

That could threaten key Russian supply lines, arms depots and air bases.

The Kremlin has consistently said the Western arms deliveries to Ukraine would ultimately not have any impact on the battlefield and only prolong the conflict and Ukrainians' suffering.

Ukraine President Volodymyr Zelensky at the time tweeted his thanks to President Joe Biden for the new aid.

"The more long-range our weapons are and the more mobile our troops are the sooner Russia's brutal aggression will end," he said.

Russia's key military objective of its invasion is the complete capture of the Donetsk region, which it already claimed to have annexed last year even as fighting there is ongoing.

The commander of Ukraine's ground forces Oleksandr Syrskyi said Tuesday that Russian forces were still working to encircle the city.

"Our main task is to wear down the masses of enemy forces and inflict heavy losses on them. This will make it possible to create the needed conditions to facilitate the liberation of Ukrainian land and speed up our victory," he added.

Russian Defence Minister Sergei Shoigu meanwhile visited ammunition production facilities in central Russia, the ministry said, and praised work to increase production of shells for the armed forces in Ukraine.

"By the end of this year, the manufacture of individual units will increase by 7-8 times," the ministry added in the statement.
