A bomb has ripped through a busy shopping centre in north-eastern Colombia, killing at least seven people and injuring more than 60. Police are blaming left-wing rebels for the blast, which happened at around 0940 local time (1440 GMT) in the city of Cucuta. The bomb went off in the underground car park of the Alejandria Shopping Centre, a favourite with the city’s poorer population, and ignited a huge fire that forced shoppers to flee in panic. The blast brought terror to a city that has one of the highest murder rates in Colombia, itself one of the most dangerous countries in the world. Rescue services, including some from just over the border in Venezuela, rushed to the scene as frightened passers-by looked on. Firefighters fought the blaze, with many of the injuries coming from smoke inhalation as people struggled to get out. The death toll rose after one of the floors of the shopping centre collapsed on rescue workers and civilians trying to help evacuate the building. Full Story
