Between March 2016 – July 2017, the majority of Abu Sayyaf kidnap for ransom operations shifted to the high seas. Seventeen ships were boarded and some sixty-five hostages from six countries were taken. In total, thirty hostages have been released (usually after a ransom was paid), seven escaped, three were rescued by Philippine security forces, and four were executed. Two others were killed during the attacks while eight seamen escaped during the shipjackings. An additional forty seamen were not taken hostage.
