Russia produces about 250,000 artillery shells per month for the war, which is almost three times more than the United States and Europe produce for Ukraine, — CNN with reference to Western intelligence.

Officials say Russia now fires about 10,000 shells a day, while Ukraine fires only 2,000. According to a representative of European intelligence, in some places of the front the ratio is even worse.

Artillery factories in the Russian Federation work around the clock, a source told CNN. In addition, Russia imports ammunition from Iran and North Korea.

Russia "launched everything it has," the intelligence official said. "Their war machine is running at full capacity," he added
