Ukraine has retaken roughly 6,000 square km (2,400 square miles) of territory this month during its counteroffensive, Volodymyr Zelenskiy has claimed, as he urged foreign allies to swiftly supply more air defence systems.
The Ukraine president used his Monday night address to declare progress in the east and south, and that further gains were being made, as Kyiv pushed to take control of almost all of Kharkiv province.
