( CNN ) -- A French journalist reporting alongside soldiers is missing in Colombia after a leftist rebel group attacked their unit , killing four people and injuring six , officials said Sunday . Romeo Langlois , who works for France 24 , is a war reporter with more than 10 years experience in the country , said Colombian Defense Minister Juan Carlos Pinzon . According to preliminary reports , Langlois was shot in his arm before he disappeared , the minister said . The attack by the Revolutionary Armed Forces of Colombia , also known as the FARC , took place in the southern Caqueta province as soldiers worked to destroy cocaine laboratories . A sergeant , two soldiers and a national police officer were killed , the defense ministry said ; six others were injured . On Sunday , French Foreign Minister Alain Juppe told French media that Langlois had been taken prisoner . France 24 reported its editors were working with authorities in both countries to gather information on the journalist . `` We know that it 's a difficult region , '' said Nahida Nakad , editorial director of Audiovisuel Exterieur de la France , of which France 24 is a part , the television network reported . `` Of course we are very worried , but we have every confidence in Romeo who knows the territory very well and is an experienced journalist . We hope that he is safe and sound , and we are in constant contact with his family . '' A FARC-sympathetic news agency that often publishes official statements from the group blamed the incident on the Colombian government . His disappearance `` is the responsibility of the government of Colombia for engaging in their ranks a foreign national as a correspondent of war , '' said an editorial posted by the New Colombia News Agency . The soldiers had destroyed five laboratories , with a total capacity to produce two tons of cocaine per week , the Colombian defense ministry said . Pinzon on Friday condemned the rebel group for a separate incident , attacks in Caqueta that left three civilians dead , one of them a baby . He reported a major blow against the rebels in the northern part of the country . A special operation by the army and national police in Antioquia killed `` Brenda , '' the second leader of the company in the area , he said . It also led to the capture of `` Richard , '' or `` The Mechanic , '' chief financial officer of the Alfonso Castellanos company of FARC in Arauca . The rebel group has been at war with the Colombian government since the 1960s , and uses kidnapping forces and civilians as a key strategy . While severely weakened in recent years , it continues to carry out kidnappings and attacks on security forces . CNN 's Marilia Brocchetto contributed to this report .
