A man who was trying to smuggle explosives from the occupied areas has been detained at the Mayorsk checkpoint at the Donbas contact line.

"Yesterday, as part of measures to counter the smuggling of banned items and material across the contact line, due to effective actions of border guards and SBU Security Service operatives, an attempt to smuggle C4 explosives from the temporarily occupied territory of Ukraine was thwarted at the Mayorsk checkpoint," the press center of Ukraine's Joint Forces Operation Headquarters said on Facebook.
