SUMY, Ukraine (Reuters) - Russia's forces may have pulled back in some parts of Ukraine more than a week ago, but the territorial defence force in the northern Sumy region is training and bracing for further attacks.
Shortly after Russian forces invaded the country on Feb. 24 in what President Vladimir Putin called "a special military operation", they crossed the border into Sumy, fighting in the streets of towns as they moved towards the capital Kyiv.
