SILCHAR, April 7: ULFA (Rajkhowa faction) celebrated its 39th raising day at the playground of Soi, 15 km from here. The event began with the hoisting of flag of the outfit followed by tributes to the martyrs. Pranjit Saikia, self styled Lt. Col., who presided over the event as chief guest recollected many a thrilling moment from the short but eventful journey of the outfit. Barak Valley, as he said, was never turned into a troubled zone by them. Rather, it was their safe haven. Often, hunted down by the security forces in the plains and hills, their cadres took refuge in the isolated pockets of this peaceful valley.
