Colombia is mourning the loss of 21 policemen in one of the deadliest terrorist attacks in recent years.

Axar.az reports citing Anadolu News Agency.

Dozens were also injured Thursday in the attack on General Santander Police Academy in the capital Bogota before a graduation ceremony.

Prosecutors identified the attacker as Jose Aldemar Rojas Rodriguez, but no group has claimed responsibility. The terrorist drove his car full of explosives into a crowd, according to Colombian officials.

Ivan Duque, Colombia’s president, called it an "insane terrorist act" and declared three days of national mourning.
