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

President Vladimir Putin said he'd sought an "open dialogue" with the West.

Almost a year after Russian President Vladimir Putin launched a full-scale invasion of neighboring Ukraine, the two countries are engaged in a struggle for control of areas throughout the east and south.

Putin's forces pulled out of key positions in November, retreating from Kherson as Ukrainian troops led a counteroffensive targeting the southern port city. Russian drones have continued bombarding civilian targets throughout Ukraine, knocking out critical power infrastructure as winter sets in.

China pushes back against US claims it may supply weapons to Russia

The United States' claims that they have intelligence showing China plans to provide weapons to Russia to assist in the ongoing war in Ukraine will impede the "political settlement of the Ukrainian crisis" and "will also further damage" China-US relations, Chinese Foreign Ministry spokesperson Wang Wenbin said during a press conference Thursday.

Wenbin called US claims of intelligence "nothing more than catching up on the wind, slandering and discrediting China."

"Since the outbreak of the crisis in Ukraine, China has been steadfast in dialogue. While standing on peace, it has persuaded and introduced peace in its own way and played a constructive role in resolving the crisis in line with the situation," Wenbin said.

IAEA says mission to Zaporizhzhia nuclear power plant 'on its way'

The head of the United Nations' nuclear watchdog announced Monday that the agency's long-awaited expert mission to the Zaporizhzhia power plant in southeastern Ukraine "is now on its way."

"The day has come," Rafael Grossi, director general of the International Atomic Energy Agency, said in a post on Twitter.

Grossi, who is leading the IAEA's "Support and Assistance Mission to Zaporizhzhia," has long sought access to the nuclear power plant, which is the largest in Europe. Russia and Ukraine have traded accusations of shelling at or near the site in recent weeks, fueling fears that the fighting could cause a nuclear disaster.

"We must protect the safety and security of #Ukraine's and Europe's biggest nuclear facility," Grossi tweeted, alongside a photo of himself with 13 other experts. "Proud to lead this mission which will be in #ZNPP later this week."

Shortly after invading neighboring Ukraine on Feb. 24, Russian troops stormed the Zaporizhzhia nuclear power plant near the town of Enerhodar, on the banks of the Dnipro River in the country's southeast. The Ukrainian workers have been left in place to keep the plant operating, as it supplies electricity across the war-torn nation.

Kremlin spokesperson Dmitry Peskov said the IAEA team will travel to the plant via Ukrainian-controlled territory, state-run TASS reported.

The area around the nuclear plant is controlled by Russian forces. Peskov said once the IAEA team enters Russian-controlled territory, all necessary security will be provided.
