Russian forces have crossed the border with Ukraine in the northeastern Sumy region and taken about 50 residents of a Ukrainian border village into Russia, Ukrainian media quoted the military as saying on Sunday, Reuters reported. 

Ukraine's public broadcaster Suspilne and the Ukrainska Pravda news outlet said Russian forces entered Ukrainian territory on Saturday night in the area of the village of Hrabovske.

Most of the local residents captured from the village were elderly people, the media said, according to Reuters.
