The French hostage held for 11 months by an Islamist group in Nigeria told French television on Thursday he made his audacious run for freedom after his captor left a key in the door by mistake. Francis Collomp, speaking on the TF1 channel, described how on the night of November 16 one of his captors entered the dungeon where he was kept to perform the ablutions required for Islamic prayer, but left the keys in the door.
