Some reports suggested that Cuban medical students were found at the FARC camp.
Earlier this month, Colombian forces entered Ecuadorian territory and attacked FARC, killing rebel leader Raul Reyes and several other leftist rebels. The attacks prompted Ecuador and Venezuela to send their own troops to their borders with Colombia.
The international community expressed its concern over sovereignty disputes.
