The NIA special court on Monday found 13 accused, including alleged Lashkar operative T. Nazeer, guilty in the case relating to recruitment of youths from Kerala for terror camps in Kashmir.
Five others were acquitted by Judge S. Vijayakumar, who is likely to pronounce the sentence on October 4.
The case relates to recruitment of men from Kerala to the camps in Kashmir for terror-related incidents in 2006.
The case was registered by police at Edakkad in Kannur district and later handed over to NIA which had filed the charge sheet in the case in February 2011.
Two accused in the case are absconding.
All the 18 accused were produced in the court, where the security was very tight.
