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.

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.

Three people were killed on Saturday in the explosion that collapsed portions of the bridge linking Russia to Crimea, a Russian official said.

The Russian Investigative Committee also said it had identified the driver of the truck that was allegedly blown up on the bridge.

Russia’s response should be tough, said Leonid Slutsky, chairman of the State Duma Committee on International Affairs.

"If the Ukrainian trace is confirmed in the state of emergency on the Crimean bridge, the consequences will be inevitable," Slutsky wrote on his Telegram channel on Saturday.

He said he has no doubt that "Kyiv is behind the organization of this attack." Ukrainian officials have not taken credit for the blast. Ukraine’s official government Twitter account tweeted the phrase “sick burn” after the explosion, but did not directly reference the blast.

"This is not just an emergency," Slutsky wrote. "It could be an act of state terrorism."

The railway infrastructure restoration has been started after the fire on the bridge was contained and extinguished, Crimean Railway said.
