Philippines vows to crush pro-Islamic State groups after two leaders killed;MANILA (Reuters) - The Philippines  military chief vowed no letup on Monday in hunting down and destroying extremist groups loyal to Islamic State, saying Marawi City would be retaken within days after the pivotal killing of two top rebel commanders. General Eduardo Ano said the successful operation to take out the two leaders was a  triumph of good over evil  and urged the 30 militants remaining in a shrinking combat zone to surrender and free hostages as troops stepped up their fight.  It will be just a matter of days before it will finally be declared that Marawi has been liberated from the clutches of terrorists,  Ano told a televised news conference.  There will be no let up. It s about time to end these terrorists.  Isnilon Hapilon, Islamic State s anointed  emir  in Southeast Asia, was shot in the head by a sniper and Omarkhayam Maute, one of two Middle East-educated  Khalifas  at the helm of the militant alliance, died of a chest wound in a targeted operation during the night, officials said. The mission came after a freed hostage disclosed the leaders  location. Ano said the bodies had been recovered and identified by experts and by captured rebels. The deaths of Hapilon and Maute is a major win for a  military criticized for its slow progress in retaking Marawi and the ease with which rebels laid siege to it on May 23, before holding the heart of the city for nearly five months. The United States has for years offered a bounty of up to $5 million for the elusive Hapilon over his activities as a faction leader of Abu Sayyaf, a group notorious for kidnapping, piracy and for beheading hostages, including foreigners. Experts say Hapilon was an Islamist ideologue who took fighters from his faction to join forces with the Maute clan, a well-funded extremist group on the island of Mindanao that emerged only last year. Abdullah Maute, the alliance s military commander, was reported killed in August, though no body was found. Ano said another key operative, Malaysian Mahmud Ahmad, was believed to be in the battle zone.   The leaders have been central to rebels regrouping, re-arming and recruiting after previous clashes over the past two years, growing stronger each time.   The alliance, Dawla Islamiya, has been bolstered by fighters from Indonesia, Malaysia, Singapore and the Middle East, among other countries. Experts say foreigners have aided funding and recruiting, preying on vulnerable youth, as shown by the presence of teenagers and child soldiers in Marawi. The military will target the destruction of all groups tied to Islamic State by the end of the year, Ano said.  There will be no let-up. It s about time to end these terrorists in Mindanao. The resistance, or what s left of it, the terrorists, will crumble. It is a dead end, there is nowhere else to go.  Rommel Banlaoi, head of the Philippine Institute for Political Violence and Terrorism Research, warned of retaliatory attacks from leaders  deputies, who would assume control.  He described Monday s operation as a  tremendous setback  to Islamic State loyalists, but said security forces should avoid complacency, boost intelligence and tackle recruitment.  We have seen many times in the past, the death of key leaders will not prevent the terrorist organizations from wreaking havoc,  Banlaoi told news channel ANC. More than 300,000 Filipinos have been displaced by the fighting, which authorities say has killed 824 rebels, 47 civilians and 162 military. The occupation has been the biggest internal security crisis in the Catholic-majority Philippines for years, compounding fears that Islamic State s extremist agenda and its advanced recruitment methods are more widespread than previously thought. Defence Secretary Delfin Lorenzana said defense chiefs would assess whether to lift martial law in Mindanao. He said all cities on the island of 22 million people were vulnerable to attack, but authorities were vigilant.;October 16, 2017
