The remaining Abu Sayyaf Group (ASG) members involved in the 2000 Sidapan hostage crisis were killed in a clash on Tuesday with military forces, the Philippine Army announced on Wednesday.

Filipino Special Forces killed the two pro-Islamic State (IS) militants, including an Abu Sayyaf sub leader, whose group kidnapped 21 mostly European and Asian holiday makers 19 years ago on the resort island of Sipadan off Sabah in Malaysia.
