The attack took place on Saturday morning in Belgorod in western Russia, about 40 kilometers from the border with Ukraine. A clip, verified by the BBC, shows something hitting a busy road in the city. A large cloud of smoke then rises from the scene as people flee running.

Request a meeting of the UN Security Council

Russia's Defense Ministry said on Telegram that at least 14 people had died, including two children. A total of 108 people are said to have been injured.

Now Russia is threatening revenge.

"This crime will not go unpunished," the Ministry of Defense wrote on Telegram.

At the same time, Russia has requested a meeting of the UN Security Council to discuss the airstrike, Reuters reports.

Large-scale Russian attacks

The Ukrainian retaliatory attack comes after nearly 120 Ukrainian towns and villages were hit by widespread Russian attacks on Friday. At least 39 people have died as a result of the attacks, according to Ukrainian President Volodymyr Zelenskyy.

Among other things, 16 people have been found dead in Kyiv. It was the single deadliest day in the capital in terms of civilian casualties since Russia launched its full-scale invasion of Ukraine in February 2022.

A security source told the BBC that Ukrainian forces reportedly struck military targets in Belgorod in retaliation for Friday's attacks. However, Ukraine has not officially commented on the incident.
