As winter turns to spring, the main question in Ukraine is how much longer Russia can sustain its offensive, and when or whether Ukraine can reverse the momentum with a counterassault.

The International Committee of the Red Cross said some 10,000 Ukrainian civilians, many elderly and with disabilities, were clinging on in horrific circumstances in Bakhmut and surrounding settlements.
Russia invaded Ukraine in February 2022, saying Ukraine's ties to the West were a security threat.
Since then, tens of thousands of Ukrainian civilians as well as soldiers on both sides have been killed.
