The Philippine president has threatened to impose martial law nationwide to combat a serious threat in the southern region of Mindanao after fighters there beheaded a police officer and took churchgoers hostage.
The ongoing violence has forced thousands to flee the city of Marawi, located about 816km south of the capital Manila.
"I will not hesitate to do anything and everything to protect and preserve the Filipino nation," Rodrigo Duterte said on Wednesday after arriving back in Manila from his trip to Russia.
Duterte has already declared martial law in the entire Mindanao.
