Russia-Ukraine updates: Putin suspends key US-Russia nuclear treaty in speech denouncing West

Roughly 66,000 Russian citizens have fled across borders into European countries amid Russian President Vladimir Putin's announcement last week of a military mobilization against Ukraine, the European Border and Coast Guard said Tuesday.

The number of Russian citizens pouring into Europe was up 30% compared to last week, according to the agency which also goes by the name Frontex.

Most of the Russian citizens are entering the European Union through Finnish and Estonian border crossing points, Frontex said on Twitter.

Putin announced on Sept. 21 that he is ordering the mobilization of 300,000 recruits to fight in Ukraine, prompting widespread protests and clashes with police across Russia.

In recent days, photos have emerged of huge traffic jams at border crossings. On Monday, the wait at the border between Russia and Georgia was estimated to be 40 to 50 hours, according to the independent Russian news outlet The Insider.

Partial results from what Ukraine and its Western allies have called "sham" referendums in four Russian-occupied regions of Ukraine show that more than 96% of voters favor becoming part of Russia, according to the state-owned Russian news agency RIA.

Voting has taken place over five days in the four areas -- Donetsk, Luhansk, Zaporizhzhia and Kherson.

The early results showed that 97.93% of voters in the Luhansk People's Republic favored joining the Russian Federation, according to the data. In Donetsk People's Republic, early results showed 98.69% favored joining the Russian Federation.

In Zaporizhzhia, 97.81% of voters cast ballots to join Russia and 96.75% of voters in Kherson also favored joining Russia, according to the data.

President Joe Biden and other Group of 7 leaders condemned Russia's "sham referenda" in occupied Ukrainian territories, calling it a Russian attempt to "create a phony pretext for changing the status of Ukrainian sovereign territory."

Leaks in a major gas pipeline running from Russia to Europe under the Baltic Sea have been detected after the Swedish seismic network said it registered blasts near the pipeline.

The leaks in the Nord Stream pipeline were first reported on Monday by Denmark's maritime authority and photos released by Denmark's Defense Command showed what appeared to be gas bubbling up to the surface.

The operator of the pipeline said the leaks were detected southeast of the Danish island Bornholm.

The underwater pipeline runs about 764 miles from Russia to Germany.

While the cause of the leaks remains under investigation, unconfirmed reports from Germany allege authorities suspect sabotage.

Ukrainian officials have accused Russia of causing leaks in a "terrorist attack," according to the BBC.

Ukrainian presidential adviser Mykhaylo Podolyak alleged the damage to the pipeline was an "an act of aggression" by Russia toward the European Union.

A continuing resolution to keep the federal government running through Dec. 16 was released by Democratic lawmakers on Tuesday morning and breaks down how $12.3 billion in the package earmarked for Ukraine will be spent.

For the first time, Congressional lawmakers, at the insistence of GOP members, will require U.S. Secretary of Defense Lloyd Austin to provide a report "on the execution of funds for defense articles and services provided Ukraine," according to a summary of the resolution.

Both houses of Congress must vote on the resolution by Friday to avoid a government shutdown.

The resolution includes $3 billion for "security assistance" for Ukraine and authorizes an additional $3.7 billion in weapons for President Joe Biden to drawdown from U.S. stocks to support Ukraine’s military. It will also authorize $35 million to respond to potential nuclear and radiological incidents in Ukraine in an apparent reply to Russian President Valdimir Putin's thinly-veiled nuclear threats in a televised speech last week.

In addition, the resolution calls for $2.4 billion to replenish U.S. stocks of weapons already sent to Ukraine and to provide Ukraine.

The new assistance for Ukraine would be on top of the $53 billion Congress has already approved through two previous bills.
