The war appears to be entering a new phase after Ukraine dealt a big blow to Russia's grip on parts of the east with a fast-moving offensive that saw Ukrainian troops enter the strategic city of Izium after five months of occupation.
Russian forces had to flee the strategic eastern city just five days after Ukrainian troops began a new offensive eastward through the Kharkiv region.
"Russians escaped and left weapons and ammo behind. City center is free," a spokesperson for the Bohun Brigade of the Land Forces of Ukraine said in a statement Saturday afternoon.
Here are more of the latest headlines from the Russia-Ukraine war:
- Ukrainian military: Russians flee strategic town in Luhansk: In a statement Sunday, the Ukrainian military's general staff said that Russian forces had abandoned the town of Svatove in Luhansk region, a town that until Saturday was still 40 kilometers (25 miles) beyond the known front line of the Ukrainian advance. Svatove has been an important hub on Russian resupply routes to the front lines further south - along the borders of Donetsk and Luhansk regions. "The occupiers have abandoned Svatove in Luhansk region," the general staff's office said in a Facebook post. "They rushed away in four Kamaz trucks, twenty Tigr AVs [armored vehicles] and stole over 20 cars of local residents." CNN cannot independently verify the Ukrainian account.

The situation is changing incredibly quickly and there are many, many more such [de-occupied] settlements."
