Mamasapano clash

The Mamasapano clash was a 2015 Philippine police operation against Islamist militants that killed 44 police commandos. The 2015 opening stated the clash is also known as the Mamasapano Massacre. Today's opening, now dominated by an infobox of belligerents and commanders, carries neither name, though massacre appears 23 times elsewhere in the article. A reader today does not learn that the operation is also commonly called a massacre.

The opening as it read in 2015

The civil conflict in the Philippines is a series of insurgencies launched by Maoist rebels , Moro rebels, and Islamists against Government forces that began in 1969 during the presidency of Ferdinand Marcos . NPA rebellion ISIL insurgency Moro conflict (until 22 February 2019) Clashes between communists and the national government [ edit ] For a chronological guide, see Timeline of the communist rebellion in the Philippines .

Official Gazette of the Republic of the Philippines . "EXCL: Army, tutulong daw sana sa SAF, kaso..." (in Filipino). "President Duterte on BOL Ratification: "The Realization of All Our Dreams" " .2 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).3 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.4 He was one of FBI's most wanted terrorists. Getulio Napeñas, the relieved SAF commander, estimates about 250 casualties 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 . The operation caught the attention of many for the relatively high number of police officers killed.5 The clash has been dubbed as the biggest loss of government elite force in history.6 The mission was called Oplan Exodus , initially misattributed as Oplan Wolverine by the local media. Oplan Wolverine refers to three of the other nine prior operation attempts targeting Marwan; Oplan Wolverine 1, 2 and 3 launched in December 2012, March and May 2014 respectively. by the PNP-SAF. The incident caused the Philippine Congress to halt the passage of the Bangsamoro Basic Law , effectively endangering the peace process between the government and the MILF. The Federal Bureau of Investigation later participated in identifying Zulkifli's body. "FVR says PNP-SAF massacre is a result of "poor direction" of commander-in-chief" .7
