On April 16, the US Congress put a hold on the remaining fiscal year 2006 funding to the Colombian Armed Forces. Congress has apparently placed the remaining funding of $55.2 million on hold out of concern about alleged links between the head of the Colombian Army and the rightist paramilitary group known as United Self-Defense Forces of Colombia (AUC), a US-designated foreign terrorist organization. Its major opponents, also on the US list of terrorist organizations, are the leftist FARC and ELN.
