Philippines army battles Isis-linked militants that invaded Marawi and took Christian hostages

Army tanks packed with soldiers have rolled into the southern Philippine city of Marawi after militants linked to Isis launched a violent siege, capturing Christians, torching buildings and setting free scores of prisoners. The Catholic church said militants were using Christians and a priest as human shields and had contacted cardinals with threats to execute hostages unless government troops withdrew.

President Rodrigo Duterte defended his decision to declare martial law on Mindanao, the Muslim-majority island where Marawi is located, to prevent the spread of extremism in the impoverished region.
The violence flared in Marawi after a botched raid by security forces on a hideout of the Maute, a militant group that has pledged allegiance to Isis. Fighters quickly dispersed, torching buildings and taking over bridges, a hospital, two jails, a church and a college. Duterte said he heard reports they may have beheaded a police chief.
He said Isis must be repelled from the Christian-majority Philippines and he would use all means possible to crush the Maute group and the allied Abu Sayyaf, whatever the consequences.

"Anyone now holding a gun, confronting government with violence, my orders are spare no one, let us solve the problems of Mindanao once and for all," said Duterte, who is from the island, after cutting short a visit to Russia and returning to Manila. "If I think you should die, you will die. If you fight us, you will die. If there's an open defiance, you will die, and if it means many people dying, so be it. That's how it is."
