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

There have been over 60 attacks on health care facilities since Russia invaded Ukraine, according to the World Health Organization, which said it "condemns these attacks in the strongest possible terms."

WHO has verified 64 such incidents between Feb. 24 and March 21 -- about two to three attacks per day -- resulting in 15 deaths and 37 injuries, the organization said in a statement Wednesday assessing the impact of the war on Ukraine's health infrastructure.

"Attacks on health care are a violation of international humanitarian law, but a disturbingly common tactic of war -- they destroy critical infrastructure, but worse, they destroy hope," Dr. Jarno Habicht, WHO representative in Ukraine, said in a statement. "They deprive already vulnerable people of care that is often the difference between life and death. Health care is not -- and should never be -- a target."

Among other health care impacts amid the war, many hospitals are limiting primary health care and essential services to focus on treating the wounded, it said. Nearly 1,000 health facilities are also close to conflict lines or in seized areas, and about half of the country's pharmacies are believed to have closed, according to WHO.

"The consequence of that -- limited or no access to medicines, facilities and health professionals -- mean that treatments of chronic conditions have almost stopped," it said.

Additionally, 1 in 4 Ukrainians have been "forcibly displaced" by the war, "aggravating the condition of those suffering from noncommunicable diseases," the organization said.

The United Nations Security Council defeated a resolution put forward by Russia on the humanitarian crisis in Ukraine.

In a symbolic gesture, 13 members of the U.N. Security Council on Wednesday abstained from voting on the resolution, which made no mention of Russia's role in creating the crisis and had been roundly criticized by members. Only Russia and China voted in favor.

No country voted against it, including the veto-wielding United States, United Kingdom or French envoys.

"To be honest, it was not necessary to veto, and I don't think the resolution that was put before us was worthy of the U.S. using its precious veto power," U.S. Ambassador Linda Thomas-Greenfield said.

Ukrainian President Volodymyr Zelenskyy marked the one-month anniversary of Russia's invasion by calling on the world's population to publicly and peacefully show their support for Ukraine.

"The war of Russia is not only the war against Ukraine, its meaning is much wider," Zelenskyy said, pivoting from speaking in Ukrainian to English during his latest address. "Russia started the war against freedom as it is."

"This is only the beginning for Russia on the Ukrainian land," he continued. "Russia is trying to defeat the freedom of all people in Europe, of all the people in the world. It tries to show that only crude and cruel force matters. It tries to show that people do not matter as well as everything else that make us people. That's the reason we all must stop Russia."

He urged the global community to "stand against the war" on March 24 -- the one-month anniversary of the start of the invasion.

"Come from your offices, your homes, your schools and universities. Come in the name of peace. Come with Ukrainian symbols to support Ukraine, to support freedom, to support life," he said. "Come to your squares, your streets. Make yourselves visible and heard. Say that people matter. Freedom matters. Peace matters. Ukraine matters."

The Ukrainian ambassador called attention to the humanitarian crisis that's unfolded in the weeks following Russia's invasion during an emergency special session of the United Nations General Assembly on Wednesday.

"Tomorrow will be another symbolic date, a month since the lives of millions of Ukrainians were split in two parts," Ukrainian Ambassador Sergiy Kyslytsya said while speaking on a resolution put forward by Ukraine. "A peaceful past full of joy and positive plans, and the present with war, suffering, death, and destruction. Thousands of Ukrainians have lost their lives over this month -- young and old, women and men, civilians and military."

Kyslytsya further detailed the "humanitarian disaster" caused by the war.

"People are starving to death in the occupied or besieged areas. People are being killed in their attempt to flee from conflict-affected areas. Cities are razed to the ground by shelling and airstrikes," he said.

The ambassador urged countries to vote in favor of the resolution put forward by his country, entitled "Humanitarian Consequences of the Aggression Against Ukraine."

"It will be critical to prevent the spillover effect for the entire world," he said. "That is why the text also mentions the impact of the conflict on food security globally, in particular in the least-developed countries, as well as energy security."
