About a quarter of Ukraine’s population has been displaced less than a month into Russia’s invasion, according to the United Nations. 

Ukraine’s population has already been declining for years, dropping from over 50 million in the 1990s to 43 million in 2022.

Now, 10 million more Ukrainians – or roughly 25% – have either been displaced inside their country or have fled as refugees to other countries as Russian forces continue their besiegement of residential communities.

Hundreds of thousands have recently fled the port city of Mariupol, where Russian forces have been accused of bombing civilian shelters. The Russian Military promised safety Sunday to the remaining Ukrainians in Mariupol if they flee the city via humanitarian corridors, but Ukrainian authorities quickly rejected the offer. 

Ukraine’s Deputy Prime Minister Iryna Vereshchuk said that as of Monday, eight humanitarian corridors have agreed to evacuate residents of areas affected by the Russian invasion, including Mariupol.

Israel balancing ‘complex considerations’ in involvement with Ukraine, Russia

After Ukraine President Volodymyr Zelenskyy pleaded for help and a stronger stance against Russia’s attack from Israel, Israeli Prime Minister Naftali Bennett said the country is managing its involvement with Ukraine and Russia “in a sensitive, generous and responsible way while balancing various and complex considerations,” according to the Associated Press.

Israel has condemned Russia’s invasion but has refrained from taking action that would anger Moscow out of concern of jeopardizing its military coordination in neighboring Syria, according to the Associated Press. 

In a video address to the Israeli parliament Sunday, Zelenskyy urged the lawmakers to take action against Russia and accused Russian President Vladimir Putin of trying to carry out a “final solution” against Ukraine. The term was used by Nazi Germany for its genocide of some 6 million Jews during World War II.

“Our people are now wandering in the world, seeking security as you once did,” said Zelenskyy, who is Jewish.

Britain officials: ‘Kyiv remains Russia’s primary military objective’

Despite a ”continued lack of progress,” Kyiv remains Russia’s primary military objective, according to British military officials.

Heavy fighting continues north of the city in north-central Ukraine, but “the bulk” of Russian forces remain more than 15 miles from the center of the city, Britain’s Ministry of Defense said in an intelligence update. 

“Russian forces advancing on the city from the north-east have stalled,” the update reads. “Forces advancing from the direction of Hostomel to the north-west have been repulsed by fierce Ukrainian resistance.”

The ministry says Russia will likely prioritize attempts to encircle the city in the coming weeks.

New Zealand offers non-lethal military assistance to Ukraine

New Zealand plans to provide $5 million New Zealand dollars ($3.5 million) in non-lethal military assistance to support Ukraine. Funds will primarily go toward the NATO Trust Fund, which provides fuel, military rations, first aid kits and more to Ukraine.  

“This is the first time New Zealand has provided direct funding to a third party organisation for non-lethal military assistance of this kind,” Prime Minister Jacinda said in a statement. “By contributing directly to the NATO Trust Fund, Ukrainian forces on the ground can benefit from the additional assistance immediately.”

New Zealand will also make a variety of surplus defense equipment available to share with Ukraine, including body armor, helmets and vests.

Deputy National Security Adviser: US can broaden sanctions against Russia

Deputy National Security Adviser Daleep Singh said Sunday that the U.S. has the ability to broaden its sanctions against Russia. 

“(We can) take the measures, take the sanctions we’ve already applied, apply them in more targets. Apply them to more sectors,” Singh told CBS’ 60 Minutes. “More banks, more sectors that we haven’t touched.”

“It’s mostly about oil and gas, but there are other sectors too,” he added. “I don’t want to specify them, but I think Putin would know what those are.”

When asked what Putin would need to do to have sanctions lifted, Singh said “we’re nowhere near that point.”

“The first thing (Putin) has to do is to stop a reckless and barbaric attack on the civilians of Ukraine,” he said. “That’s not happening.”

What is a war of attrition?

Following weeks of Russian forces besieging residential cities and the Ukrainian military attempting to sever supply lines, Western governments and analysts say Vladimir Putin’s invasion of Ukraine is beginning to become a war of attrition. But what does that mean?

Attrition warfare refers to wearing down an opponent to the point of exhaustion. One of the most famous examples of a war of attrition was World War I, which consisted of lengthy and prolonged battles, largely fought in trenches.

Britain’s defense intelligence chief said last week Russia was shifting to a ”strategy of attrition” after unexpected pushback from Ukrainian forces and failure to capture its largest cities. Chief of Defense Intelligence Lt. Gen. Jim Hockenhull said Russian forces’ new strategy “will involve the reckless and indiscriminate use of firepower. This will result in increased civilian casualties, destruction of Ukrainian infrastructure and intensify the humanitarian crisis.”

Mariupol’s city council accused the Russian military of bombing an art school Sunday where about 400 people had taken shelter. Days earlier, Russian forces bombed a theater in the strategic port city where civilians took shelter.
