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.

A year into the war in Ukraine, 13 million people have been displaced, including nearly 8 million refugees across Europe and more than 5 million internally displaced in Ukraine, the U.N. High Commissioner for Refugees said in a statement Thursday.

"The vast majority of refugees and internally displaced Ukrainians – some 77% and 79%, respectively – want to return home one day, however, only 12% of both refugees and [internally displaced people] plan to do so in the next three months," the UNHCR said in a press release.

Air raid sirens went off across Ukraine on Wednesday due to jets taking off in Belarus.

There were four strikes from Russian S-300 missiles on industrial infrastructure facilities in central Kharkiv, the head of Kharkiv's Regional Military Administration Oleh Synegubov said.

Two men, ages 46 and 57, were injured from the attacks. They have both been hospitalized.

In Izyum, a city in the Kharkiv region of Ukraine, a 55-year-old civilian stepped on a "petal" mine. He was hospitalized with an explosive wound, Synehubov said.

One person was killed and another person was injured from fighting in the Donetsk region of Ukraine on Tuesday, the head of the Donetsk Regional Military Administration Pavlo Kyrylenko said.

Russia has suspended the New START nuclear arms treaty with the United States, Russian President Vladimir Putin said.

But he emphasised that Russia was not leaving the treaty yet, only suspending its participation in its for the time-being.

He blamed the suspension on the West, saying relations had degraded and that it was impossible currently to allow American inspections of Russian strategic nuclear sites.

Putin's decision was announced on Tuesday as he gave an annual state-of-the-union speech in Moscow, days ahead of the one-year anniversary of the invasion into Ukraine.

He also accused the United States of considering restarting nuclear bomb tests and threatened that Russia would hold them too if that happened.

That will be interpreted as a veiled threat in relation to the war in Ukraine -- experts have feared Russia might conduct a nuclear bomb test to intimidate Kyiv and its Western allies. Putin ordered Russia’s military to prepare the possibility to hold a test.

“Some actors in Washington are thinking about testing nuclear weapons,” he said. “The defense ministry and RosAtom must prepare also to conduct nuclear tests in case of necessity. But Russia will not conduct it first.”
