Verified footage showed a burning lorry at the scene of the attack in Cali
Verified footage shared on social media shows the aftermath of a bombing on a busy street outside of an air force base in the Colombian city of Cali.
The blast, which the government has blamed on dissident factions of the Revolutionary Armed Forces of Colombia (FARC) group, occurred just over 100m (330ft) from the base entrance. Videos filmed in the immediate aftermath show bodies on the ground, burning vehicles, and damage to nearby shops.
Local reports say the blast was caused by a vehicle bomb and a destroyed lorry can be seen at the centre of the scene.
Another vehicle was also filmed abandoned with several barrels visible in the back, which has prompted speculation a second truck-bomb failed to detonate.
At least six people were reportedly killed and more than 60 injured in the attack – making it one of the deadliest urban attacks by FARC-related dissident groups in recent years.
Although the FARC formally demobilised following a 2016 peace agreement, dissident factions rejected the deal and remain active.
To geolocate the footage, we matched a badly damaged Dollarcity shop which is seen in several videos to Google Maps imagery and confirmed the location further by identifying the air base entrance on Google Street View. We also carried out reverse image searches to confirm the material was newly posted.
