2025 Sumy airstrike

The 2025 Sumy airstrike was a missile attack carried out by the Russian Armed Forces on 13 April 2025 against the city of Sumy in northeastern Ukraine, during the ongoing Russian invasion of Ukraine. The strike employed two ballistic missiles—identified as Iskander‑M missiles—targeting the city centre during Palm Sunday church services. According to Ukrainian authorities, the attack killed at least 35 people, including two children, and injured 129 others, of whom 15 were children. The incident was the deadliest attack on Ukrainian civilians since 2023. [1][2][3]

Background
Sumy Oblast borders the Russian‑controlled Kursk Oblast and had been subject to intensified Russian aerial operations in the weeks preceding the attack. Russian forces had increased missile strikes in the region while also advancing Ukrainian military units from positions in the adjacent Kursk area. Minor settlements in Sumy Oblast had reportedly fallen under Russian occupation shortly before the airstrike. [1]

The attack
At approximately 10:20 a.m. (UTC+3), two ballistic missiles struck densely populated areas of Sumy’s city centre. Ukrainian officials described the weapons as ballistic missiles equipped with cluster munitions, though Russian state media reported the use of high‑explosive incendiary (HEI) munitions. [4][5] The missiles hit near the Congress Center of Sumy State University, a venue where a planned military award ceremony for the 117th Territorial Defense Brigade was to be held. Ukrainian officials, including the regional military administration head Volodymyr Artyukh, indicated that the ceremony was the intended target, a claim later dismissed by Reuters and other outlets as unverified. [6][7][8] Russian officials, including Kremlin spokesman Dmitry Peskov, asserted that the gathering of military personnel made the site a legitimate military target. [9]

Casualties and damage
The strike resulted in at least 35 fatalities and 129 injuries. Among the dead were civilians, including a child, and a number of military personnel; reports named colonel Yuri Yula, commander of the 27th Rocket Artillery Brigade, as one of the military casualties. The attack caused extensive damage to residential buildings, a trolleybus, and other infrastructure in the city centre. [10][11][12]

Aftermath
In the wake of the attack, Volodymyr Artyukh was dismissed from his position as governor of Sumy Oblast for allegedly endangering civilians by organizing the ceremony. International reactions condemned the strike as a possible war crime, citing the use of cluster munitions in a densely populated area. The incident contributed to heightened diplomatic pressure on Russia from the United States and European allies. [13][14]
