One person was killed and 21 others were injured in a bomb attack on a nightclub in a northeast Colombian city of Cucuta on Sunday.
According to local police, an unidentified man detonated a grenade inside the downtown club in the early hours of the morning when the club was full.
Cucuta police chief Colonel Carlos Rodriguez told newspaper El Tiempo that investigators are trying to find out who detonated the grenade and whether the attacker is either the deceased person or among the injured.
Additionally, authorities are investigating whether the attack is related to tensions between drug traffickers.
According to El Tiempo, Sunday’s grenade attack was the seventh this year in Cucuta, a city on the Venezuelan border and a hub for smuggling and drug trafficking.
