( CNN ) -- Shoulder-launched anti-tank weapons purchased by Venezuela have ended up in the hands of guerrillas , Colombian Vice President Francisco Santos said . Venezuelan Foreign Minister Nicolas Maduro talks on the phone with President Hugo Chavez in Caracas Monday . In an interview with Caracol Radio Monday , Santos addressed local reports of anti-tank weapons manufactured in Sweden being seized from members of the Revolutionary Armed Forces of Colombia , or FARC , and traced to Venezuela . `` This is not the first time that this happens , '' Santos said . `` In several operations in which we have recovered weapons from the FARC , we have found powerful munitions and powerful equipment , including anti-tank weapons , from a European country that sold them to Venezuela and that turned up in the hands of the FARC . '' The weapons have been identified as AT4 shoulder-fired rockets manufactured by Saab Bofors Dynamics in Sweden , according to Jane 's Defence Weekly . They were seized in 2008 from a guerrilla base , the Colombian magazine Semana reported . Jan-Erik Lovgren , the Swedish official who oversees weapon exports , told Radio Sweden on Monday that his country stopped selling weapons to Venezuela in 2006 . Venezuela on Monday denied allegations that they gave the weapons to the guerrilla group . `` To me it seems that this is a new attack against our government based on lies , '' Venezuelan Minister of the Interior and Justice Tareck El Aissami said at a news conference Monday . `` We absolutely deny that our government or our institutions are providing assistance to criminal and terrorist organizations , '' El Aissami told reporters . `` It 's laughable , it sounds like a cheap film made by the American government . '' Previous instances of Venezuela 's government being accused of aiding the FARC include one last year , when the U.S. Treasury Department accused two senior Venezuelan intelligence officials and one former official of assisting the guerrillas with drug trafficking . The department froze any assets the three men may have under U.S. jurisdiction and prohibited Americans from conducting business with them .
