The United Nations says it needs $5.6 billion to help address the humanitarian crisis in Ukraine and to help the millions who have fled Ukraine since Russia’s invasion began almost a year ago. The U.N. estimates nearly 22 million Ukrainians depend on humanitarian assistance.

This comes as NATO says Russia’s eastern offensive has begun, as Moscow aims to capture the strategic city of Bakhmut. The Ukrainian military ordered aid groups to leave the city earlier this week. Kyiv says, though, it has repelled Russian attacks on Luhansk. Meanwhile, the Pentagon is seeking to restart a program to place U.S. special operations forces inside Ukraine.

In other news on the war, a State Department-backed report has accused Russia of holding at least 6,000 Ukrainian children at facilities in occupied Crimea and Russia. State Department spokesperson Ned Price criticized the Russia program on Tuesday.

Ned Price: “Putin seeks to rob Ukraine of its future by taking its children. Russia’s system of forced relocation, reeducation and adoption of Ukraine’s children is a key element of the Kremlin’s systematic efforts to deny and suppress Ukraine’s identity, its history and its culture.”
