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

The European Union Council on Tuesday imposed a fourth package of economic and individual sanctions, including restricting the export of luxury goods to Russia and banning new investments in Russia's energy sector.

Sanctions also target "key oligarchs, lobbyist and propagandists pushing the Kremlin’s narrative on the situation in Ukraine," the Council said in a statement.

"The aim of the sanctions is that President Putin stops this inhuman and senseless war," Josep Borrell, High Representative of the European Union for Foreign Affairs and Security Policy, said in a statement.

The United Kingdom is expanding sanctions targeting over 300 people including former Russian President Dmitry Medvedev and oligarchs with an estimated worth of more than $94 billion.

The U.S. is also expanding sanctions, including against Russian Ministry of Defense officials.

The State Department is also implementing a new visa ban policy against Russian officials who have "cracked down on Russian citizens who have taken to the streets to protest their government's brutal campaign in Ukraine" and "are responsible for suppressing dissent in occupied areas of Ukraine."

In retaliation for sanctions from the U.S., Russia’s foreign ministry has announced personal sanctions against President Joe Biden and many top administration officials including Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin. The sanctions also target Biden’s son, Hunter, and former Secretary of State Hillary Clinton.

Two people were killed on Tuesday morning after Russian forces shelled residential areas in Kyiv, officials said.

The sound of large explosions echoed across Kyiv before dawn from what Ukrainian authorities said were artillery strikes. The shelling ignited a huge fire and a frantic rescue effort in the Svyatoshyn neighborhood.

Shockwaves from an explosion also damaged the entry to a downtown subway station that has been used as a bomb shelter. City authorities tweeted an image of the blown-out facade, saying trains would no longer stop at the station.

Residents of Kherson, Melitopol and Berdyansk, cities occupied by Russian forces, have held “multiple” demonstrations protesting the occupation, the U.K. Defence Ministry said on Tuesday.

Protests in Kherson came as Russia may be making plans for a “referendum” to legitimize the region as a Russian-backed “breakaway republic,” similar to Donetsk, Luhansk and Crimea, the Ministry said.

“Further protests were reported in the city yesterday with Russian forces reportedly firing warning shots in an attempt to disperse peaceful protesters,” the Ministry said.

Russia is likely to “make further attempts to subvert Ukrainian democracy,” the update said.

“Russia has reportedly installed its own mayor in Melitopol following the alleged abduction of his predecessor on Friday 11 March,” the update said. “Subsequently, the Mayor of Dniprorudne has also reportedly been abducted by Russian forces.”

Ukrainian President Volodymyr Zelenskyy updated the status of negotiations with Russia in his latest address Monday, saying the latest talks went "pretty good" and will continue tomorrow.

Zelenskyy also addressed Russian troops, telling them they would be treated "decently" should they surrender.

"On behalf of the Ukrainian people, I give you a chance -- chance to survive," Zelenskyy said. "You surrender to our forces, we will treat you the way people are supposed to be treated. As people, decently."

Zelenskyy also thanked the producer at a Russian state news channel who appeared on camera behind an anchor and held up an anti-war sign. She was later arrested.

"I am grateful to those Russians who do not stop trying to convey the truth," he said. "To those who fight disinformation and tell the truth, real facts to their friends and loved ones. And personally to the woman who entered the studio of Channel One with a poster against the war."
