Mamasapano clash

The Mamasapano clash, also known as the Mamasapano Massacre, was a police operation, codenamed Oplan Exodus, which took place on Sunday, January 25, 2015, at Tukanalipao, Mamasapano, Maguindanao, by Special Action Force (SAF) of the Philippine National Police (PNP) (allegedly joined by United States Army Special Forces) against the Bangsamoro Islamic Freedom Fighters (BIFF) and the Moro Islamic Liberation Front (MILF). The operation was intended to capture or kill wanted Malaysian terrorist and bomb-maker Zulkifli Abdhir and other Malaysian terrorists and/or high-ranking members of the BIFF.

Originally a mission to serve arrest warrants for high-ranking terrorists, it led to the deaths of 44 members of SAF, 18 from MILF and 5 from the BIFF, and several civilians, and the death of Zulkifli Abdhir confirmed by the FBI and the PNP at 6:30 p.m. of February 4, 2015 due to a matching DNA result. He was one of FBI's most wanted terrorists. Getulio Napeñas, the relieved SAF commander, estimates about 250 deaths from the combined MILF, BIFF, and private militias during the encounter although this was not confirmed and was met with skepticism since aside from the fact that there was no actual body count, there is no acceptable level of evidence to prove his claim. Napenas' estimate was also debunked by the MILF and by the local government of Mamasapano.
