Russia regularly strikes Ukrainian civilian infrastructure, including residential buildings and energy infrastructure, as it continues to wage its war.
A Russian drone attack in northeastern Ukraine's Sumy Oblast killed two brothers and a married couple, while a missile strike damaged a production facility belonging to U.S. multinational company Mondelez, authorities reported Feb. 21.
The two brothers were first injured by an explosive device dropped by a drone and taken to the hospital, Sumy Oblast Governor Oleh Hryhorov reported.
"On the way to the hospital, the Russians deliberately attacked the emergency vehicle with a strike drone," he added. The second Russian strike killed the two siblings.
