Russia-Ukraine updates: US sanctions Russian military shipbuilder, diamond miner

The Minister for Foreign Affairs of Ukraine, Dmytro Kuleba, called on the International Criminal Court and other international organizations to investigate Russians committing war crimes and crimes against humanity.

"I urge the International Criminal Court and international organizations to send their missions to Bucha and other liberated towns and villages of the Kyiv region, in cooperation with Ukrainian law enforcement agencies, to collect all evidence of Russian war crimes as carefully as possible," Kuleba said Sunday on Times UK radio.

"We are still collecting and looking for bodies, but the toll has already gone into the hundreds. Dead bodies lie on the streets. They killed civilians while in and out of these villages and towns," he said.

Plumes of dark smoke rose on Sunday over Odessa, Ukraine, after an early morning Russian attack on the strategic and historic port city.

Missiles struck critical infrastructure facilities in the southern city, which sits on the Black Sea, Ukraine’s southern command announced. Casualties have not yet been reported.

According to the Ukrainian military, some Russian missiles were shot down by air defenses.

Missiles first hit Odessa on the opening night of Russia's invasion and again late last month. Residents have been bracing for Russia to launch an offensive to take the city.

Russia’s military on Sunday claimed the attack destroyed an oil refinery and three fuel depots, which had been supplying fuel to a nearby group of Ukrainian troops.

Ukrainian President Volodymyr Zelenskyy issued a new address Saturday updating the progress of the country's defense against Russian forces.

Ukrainian forces are regaining control of the Kyiv and Chernihiv regions, according to the president.

"There are more and more Ukrainian national flags in the areas that have been temporarily occupied," Zelenskyy said.

Zelenskyy, however, said his country hasn't received any new weapon systems from the West and chastised Western allies.

"Every Russian missile that hit our cities and every bomb dropped on our people, on our children, only adds black paint to the history that will describe everyone on whom the decision depended; [the] decision whether to help Ukraine with modern weapons," he said.
