After some stunning successes over the summer, it appears that the Ukrainian army is now facing a much tougher fight on multiple fronts in the east and south. Sviatoslav Yurash, Ukraine's youngest lawmaker, told ABC News Ukrainian forces are "seeing casualties mount up."

"The reality is dire," he told ABC News in an interview in Kyiv. "We are facing an onslaught of unparalleled proportions."

Yurash, who is fighting in the military, recently returned from what he called "hell-like" conditions in the eastern Donbas.

"The reality is an artillery barrage day in, day out, night in, night out," Yuras said.

Yurash said that Ukrainian troops still "lack" equipment.

Referring to U.S. support, he said, "nothing is enough, and everything is very welcome," pointing out that the Ukrainians are fighting along 600 miles of front lines. Weapons systems such as the U.S.-supplied Howitzers and HIMARS are prioritized to particular points of the conflict zone.

He said additional support from the West is "desperately needed."

Russian President Vladimir Putin launched a rhetorical attack on the West, claiming it believes its world view is universal.

"The policy of the West is bloody and dirty, it denies the sovereignty of countries and peoples," Putin said, delivering an address at the Valdai Club, a think tank forum.

Putin said that the “rules-based order" proposed by the West is designed to enable it to live without rules at all. He claimed that the West has no unity, calling it a "conglomerate."

He described the destruction of the European Gas pipelines as “beyond all reason.”

Russia is threatening to target commercial satellites from the United States and its allies if they become involved in the war in Ukraine.

"Quasi-civilian infrastructure may be a legitimate target for a retaliatory strike," Konstantin Vorontsov, deputy director of the non-proliferation and arms control department at the Russian Ministry of Foreign Affairs, was quoted as saying by state media on Thursday. "We are talking about the involvement of components of civilian space infrastructure, including commercial, by the United States and its allies in armed conflicts."
