Colombian authorities are investigating an attack by an armed group that opened fire on a convoy of mining company buses, leaving at least four workers injured on Tuesday.
The incident occurred in the municipality of Codazzi in the northern Cesar department where a group of heavily armed men opened fire on buses carrying workers for the international mining company Drummond, reported newspaper El Espectador.
No armed groups have been attributed to the attack so far, although authorities have not ruled out the possibility that it was the FARC‘s 41st Front.
The U.S. based Drummond Company is primarily engaged in the business of mining, purchasing, processing and selling of coal and coal derivatives. The mining company is based in Alabama and has international operations in Colombia serving customers mainly in the United States and Europe.
Colombia has seen an increased amount of attacks on its infrastructure over the past year, especially the oil and mining industries, which have been mostly attributed the country’s largest guerrilla group FARC and ELN rebels.
