Ukraine said on Tuesday it aimed to liberate all of its territory after driving back Russian forces in the northeast of country in a rapid offensive, but called on the West to speed up deliveries of weapons systems to back the advance. 

Since Moscow abandoned its main bastion in northeastern Ukraine on Saturday, marking its worst defeat since the early days of the war, Ukrainian troops have recaptured dozens of towns in a stunning shift in battleground momentum. Fighting was still raging in the northeastern Kharkiv region, Deputy Defence Minister Hanna Malyar said on Tuesday, saying Ukraine’s forces were making good progress.
