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

At least 925 civilians, including 75 children, have been killed in Ukraine since Russian forces invaded on Feb. 24, according to the latest figures from the Office of the United Nations High Commissioner for Human Rights (OHCHR).

Meanwhile, at least 1,496 civilians, including 99 children, have been injured, OHCHR figures show.

The tallies are civilian casualties that occurred in Ukraine from Feb. 24 to March 20 and have been verified by OHCHR, though the agency cautioned that the true numbers are believed to be "considerably higher."

"Most of the civilian casualties recorded were caused by the use of explosive weapons with a wide impact area, including shelling from heavy artillery and multiple-launch rocket systems, and missile and air strikes," OHCHR said in a statement late Monday. "OHCHR believes that the actual figures are considerably higher, especially in Government-controlled territory and especially in recent days, as the receipt of information from some locations where intense hostilities have been going on has been delayed and many reports are still pending corroboration."

Russia claimed Tuesday that its troops have captured nine more localities in Ukraine.

According to a statement from the Russian Ministry of Defense, units of the Russian Armed Forces have advanced another 6 kilometers (about 3.7 miles) and have taken control of the southeastern village of Urozhaine in the Donetsk oblast, some 65 miles north of the besieged port of Mariupol where many civilians remain trapped under Russia bombardment.

Meanwhile, the defense ministry said Russia-backed separatist forces of southeastern Ukraine's disputed Donbas region have also advanced and captured eight more areas in the Donetsk and Luhansk oblasts.

Russian Deputy Foreign Minister Sergey Ryabkov on Tuesday denied allegations that Russia might be planning to use biological or chemical weapons in Ukraine.

"We have neither of these," Ryabkov told reporters in Moscow. "What the Americans are saying are malicious insinuations -- we've heard them all the time and we've given exhaustive answers to them for a long time. The problem is, the U.S. has no habit of listening to anyone but itself."

Ryabkov's comments came after U.S. President Joe Biden accused Russian President Vladimir Putin of falsely claiming that the United States and Ukraine are developing biological or chemical weapons for use against Russia -- rhetoric that Biden said shows Putin is considering using those types of deadly weapons in Ukraine.

"He's already used chemical weapons in the past, and we should be careful of what's about to come," Biden said Monday during remarks at the Business Roundtable's CEO Quarterly Meeting in Washington, D.C.

Russian Deputy Foreign Minister Sergey Ryabkov warned Tuesday that the United States should stop supplying Ukraine with weapons and making threats to Moscow in order to "preserve relations" with Russia.

"They simply need to stop in their escalation, both verbal escalation and in terms of stuffing the Kyiv region with weapons. They need to stop producing threats to Russia," Ryabkov said while answering questions from reporters in Moscow. "Meanwhile, if they do manage to somehow positively influence Kyiv, something that I not just doubt, but I am confident that it will not happen, unfortunately, then I think there will be a certain prospect for normalizing relations."

"For now, we see a downward tendency in relations with our country through the fault of the U.S.," he added. "We regret it, but it does not impact our determination to move toward accomplishing the goals of the special military operation and to adapt to the circumstances related to the American sanctions and the sanctions imposed by European satellites of the U.S. at its behest."

When asked whether Moscow plans to recall its ambassador, Ryabkov told reporters that the future of Russia-U.S. relations depends on Washington.

"A note of protest was passed to the American ambassador yesterday. It said that the current developments put these relations on the brink of a breakup," he said. "There is nothing here beyond what was said there: that the question is about a policy that the U.S. will choose."
