After two years of captivity by Abu Sayyaf militants, Swiss bird watcher Lorenzo Vinceguerra escaped while Philippine troops fired rounds into the Abu Sayyaf camp in Patikul on Sulu. During the clash, Vinceguerra killed one of his captors, militant subcommander Juhurim Hussien, and was wounded by militant gunfire. In pursuit, Philippine troops later killed five Abu Sayyaf militants in Talipao on Sulu. Abu Sayyaf militants on Sulu are thought to be still holding more than 10 hostages.
