Islamic State-linked militants besiege Philippine city

Army tanks packed with soldiers rolled into a southern Philippine city today as gunfire and explosions rang out after militants linked to the Islamic State group torched buildings, seized more than a dozen Catholic hostages and raised the black flag of ISIS.
At least 21 people have died in fighting that erupted late Tuesday, when the army raided the Marawi hideout of Isnilon Hapilon, who is on Washington's list of most-wanted terrorists and has a USD 5 million bounty on his head.
The operation went wrong as the militants called in reinforcements and swept through the mostly Muslim city of 200,000 people. Hapilon's whereabouts were not clear, but there was no indication he was captured in the raid.

President Rodrigo Duterte declared martial law across the southern third of the nation, home to some 22 million people, and warned he may expand it nationwide.
He vowed to be "harsh."
"If I think that you should die, you will die," he said yesterday. "If you fight us, you will die. If there is open defiance, you will die. And if it means many people dying, so be it."

As details of the attack in Marawi city emerged, fears mounted that the largest Roman Catholic nation in Asia could be falling into a growing list of countries grappling with the spread of influence from the Islamic State group in Syria and Iraq.

Thousands of people were fleeing the city Thursday, jamming their belongings into cars. Plumes of black smoke rose in the distance and two air force helicopters could be seen flying over the city center.
Mohammad Usman, a 49-year-old Marawi resident, said some people are likely trapped with no way out.
"At night we can hear the gunfire. I'm just praying that the bullets will not find its way to my house and hit us," he said as he left the city. "I hope that the bombs will not land nearby and harm us."
Although much of the city is sealed off, disturbing details were trickling out.

Duterte said a local police chief was stopped at a militant checkpoint and beheaded. Military chief of staff Gen. Eduardo Ano said the militants erected Islamic State flags at several locations.
Marawi Bishop Edwin de la Pena said the militants forced their way into the Marawi Cathedral and seized a Catholic priest, 10 worshippers and three church workers.
Martial law allows Duterte to use the armed forces to carry out arrests, searches and detentions more rapidly. He has repeatedly threatened to place the south, the scene of decades-long Muslim separatist uprisings, under martial law.
But human rights groups have expressed fears that martial law powers could further embolden Duterte, whom they have accused of allowing extrajudicial killings of thousands of people in his crackdown on illegal drugs.

Hapilon, an Arabic-speaking Islamic preacher known for his expertise in commando assaults, pledged allegiance to the Islamic State group in 2014. He is a commander of the Abu Sayyaf militant group and was wounded by a military airstrike in January.
While pursuing peace talks with two large Muslim rebel groups in the south, Duterte has ordered the military to destroy smaller extremist groups which have tried to align with the Islamic State group.
