Law enforcement has apprehended 11 suspects, including all four gunmen directly involved in perpetrating the deadly assault, following a pursuit involving vehicles in Russia's Bryansk region.

The FSB disclosed that the attackers had ties in Ukraine and were en route to the border following the terrorist attack. They intended to cross the Russian-Ukrainian border, having established pertinent contacts on the Ukrainian side.
