Ukraine's armed forces have recaptured large swaths of territory and are making "significant gains" against Russia's occupation of the northwest region of Kharkiv, the British defense ministry said in an intelligence briefing Sunday.

"The Ukrainian success resulted from skillful campaign design and execution that included efforts to maximize the impact of Western weapons systems such as HIMARS," the Institute for the Study of War said in its latest assessment of the war in Ukraine, referring to High Mobility Artillery Rocket systems.
