Duterte: Philippine militants 'hungry' for caliphate

Philippine President Rodrigo Duterte said Saturday Abu Sayyaf Islamic militants were hungry to establish a caliphate, as he toughens his stance on the kidnap-for-ransom group accused of a deadly bombing in his home city this month.

The fiery leader, who has threatened to eat the militants alive in a bloodthirsty vow of revenge for the attack in Davao that killed 15 people, said the group was no longer just after money from criminal activities.
