End of Peaceful Period Brings Return to Violence
The most stable ceasefire since 2014 began to break down in October 2020, with renewed fighting in eastern Ukraine ending several months of relative calm and raising fears of broader escalation.
Key Facts

Root Causes
The breakdown reflected persistent underlying issues:
