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.

A new barrage of missiles strikes was launched against Ukraine on Monday, hitting targets across the country, including the capital city of Kyiv, officials said.

Casualties and damage from the attacks were being assessed, Ukrainian officials said.

The majority of the missiles were shot down by air defense forces, Ukrainian officials said.

Ukrainian air force spokesman Yuriy Ihnat said the Russians launched missiles from the Volgodonsk, Caspian and Black seas.

The strikes damaged two infrastructure objects in the Odesa region, leaving the area without electricity and running water, officials said. One person was hospitalized, according to Ukrainian officials.

Odesa Mayor Gennadiy Trukhanov said a missile hit a substation that supplies the city of Belvaevska's pumping station with electricity.

According to the office of Ukrainian President Volodymyr Zelenskyy, missile strikes in the Zaporizhzhia region killed two people and injured three others, including a toddler, in the village of Novosofiyivka.

Explosion were also heard in Cherkasy, Kharkiv, Dnipropetrovsk, Vinnytsia, Khmelnytskyi, Kherson and Cherkasy, officials said.

The missile strikes followed reports from Russian media outlets that drones were used to bomb two military air bases in Russia, hundreds of miles from the Ukrainian border.

Ukrainian officials have not claimed responsibility for the drone attacks, but Mykhailo Podolyak, a top adviser to Ukraine’s president, posted a cryptic tweet, saying "if you launch something very often into the airspace of other countries, sooner or later the unknown flying objects will return to the place of departure."
