As 50,000 Russian troops amass, Ukraine's Sumy Oblast braces for potential large-scale offensive

"Reports of an imminent Russian summer offensive and troop build ups on Ukraine's border

are raising alarms in Sumy Oblast and fears that a large-scale assault could be on the horizon.
Russian President Vladimir Putin said he had ordered his military to create a "security buffer zone" along the border, and President Volodymyr Zelensky later claimed 50,000 of Moscow's troops were amassed "in the direction of Sumy."
"These are trained combat units — airborne troops, marines, those that were specially transferred to displace our troops," a source in Ukraine's defense forces told the Kyiv Independent." KI
