The Dos Palmas kidnappings was a hostage crisis in the southern Philippines that began with the seizing of twenty hostages from the affluent Dos Palmas Resort on a private island in the Honda Bay, Palawan, by members of Abu Sayyaf on May 27, 2001, and resulted in the deaths of at least five of the original hostages. Three of these hostages were American citizens, Guillermo Sobero, and a married missionary couple, Gracia and Martin Burnham. At least 22 Filipino soldiers were killed in attempts to apprehend the captors and free the hostages in the 12 months following the initial hostage taking. An unknown number of captors were killed by government forces.
