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

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.

A massive line of traffic continued to grow Monday at the border between Russia and Georgia as huge numbers of Russians seek to flee the country amid fears they will be drafted to fight in the war in Ukraine.

Drone video, posted on Twitter by the independent Russian news outlet The Insider, showed hundreds of cars and trucks backed up for miles at the Verkhny Lars border between the two countries.

The Insider reported that people are waiting 40-50 hours in the line to cross.

Tens of thousands of Russians are trying to flee the country following Russian President Vladimir Putin’s announcement last week of a military mobilization of 300,000 more troops against Ukraine. Besides the Russia-Georgia border, large crowds of people attempting to leave the country have been packing border crossings into Finland, Kazakhstan, Mongolia and others.

More clashes broke out Monday in Russia's Dagestan capital city, as police tried to disperse hundreds of protesters demonstrating against the Kremlin’s military mobilization of men to fight in Ukraine.

Videos circulating on social media showed scuffles between protesters and police in Makhachkala.

On Sunday, there were violent clashes in Dagestan, with police firing warning shots and people angrily shouting chants against the mobilization.

Russian President Vladimir Putin announced last week that he is mobilizing 300,000 more troops against Ukraine.

The announcement sparked major protests in Moscow and at least 30 other cities across Russia over the weekend. At least 17 military recruitment offices have been targeted with arson attacks. A man was detained by authorities on Monday after he allegedly opened fire on a recruitment center in Siberia, severely injuring a recruitment officer.
