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

Several NATO allies have announced additional support for Ukraine during their two-day NATO defense ministers meeting.

Canada said Wednesday it is planning $47 million Canadian dollars more in military aid, including winter equipment, drone cameras and satellite communications, in the coming weeks.

The British government announced Thursday it would provide missiles for advanced NASAM anti-aircraft systems that the Pentagon plans to send to Ukraine. The U.K. also is sending hundreds of aerial drones for information gathering and logistics support, plus 18 howitzer artillery guns.

France promised more artillery, anti-aircraft systems and missiles, with President Emmanuel Macron telling France 2 television on Wednesday that they will provide Ukraine with CAESAR mobile artillery units to lead the counteroffensive, as well as radars, unspecified military systems and missiles.

The Netherlands also announced Wednesday it will send additional advanced air defense missiles.

The United Nations General Assembly overwhelmingly voted to pass a resolution censuring Russia for its attempted annexation of four Ukrainian regions on Wednesday.

In a record number of ayes for resolutions supporting Ukraine since the onset of the war, 143 countries voted in favor of the resolution, while five voted against and 35 abstained.

The five countries voting against the measure were Russia, three allies that have consistently aligned themselves with Moscow in the chamber--- Syria, North Korea, Belarus -- as well as Nicaragua.

A senior administration official previously set the bar for success of the measure at 100 votes -- the same number that backed a resolution denouncing Russia's annexation of Crimea in 2014.

U.S. ambassador to the U.N. Linda Thomas-Greenfield called it a "monumental day" for the body.

"This means that, in the eyes of the world, Ukraine's borders remain the same," she said on Twitter.

Power has been restored to the Zaporizhzhya nuclear power plant after it lost all of its external power for the second time in five days.

The plant's operator said the outage was caused by shelling damage to a far-off sub-station.

The plant's backup diesel generators had provided electricity for its nuclear safety and security functions, according to the International Atomic Energy Agency.

“This repeated loss of #ZNPP’s off-site power is a deeply worrying development and it underlines the urgent need for a nuclear safety & security protection zone around the site," IAEA Director General Rafael Grossi said in a tweet.

Europe's largest nuclear power plant has lost external electricity for the second time in five days, the head of the United Nations' nuclear watchdog said Wednesday.

International Atomic Energy Agency Director-General Rafael Mariano Grossi said he was informed of the situation at the Zaporizhzhia nuclear power plant in southeastern Ukraine on Wednesday morning. The Russian-occupied plant's "back-up diesel generators are now providing electricity for its nuclear safety and security functions," according to Grossi.

“This repeated loss of #ZNPP’s off-site power is a deeply worrying development and it underlines the urgent need for a nuclear safety & security protection zone around the site," Grossi said in a post on Twitter.

On Tuesday, Ukraine's state nuclear energy company Energoatom alleged that Russian forces have kidnapped Valery Martynyuk, the deputy head of the Zaporizhzhia nuclear power plant, and are detaining him in an unknown location. In a statement to ABC News, Energoatom accused Russian troops of trying to get information about the personal affairs of Zaporizhzhia employees in order to force Ukrainian personnel to work at Russia's state nuclear agency Rosatom as soon as possible.
