Philippine President Rodrigo Duterte won martial law powers across the southern third of the country for one more year on Wednesday to combat Islamic militants and leftist rebels, as Congress brushed aside fears of a looming dictatorship. Duterte declared martial law in Mindanao in May as fighting raged in Marawi City between government forces and militants linked to the Islamic State (IS) group. More than six months after Filipino and foreign fighters claiming allegiance to Islamic State stormed this lakeside city, setting off a months-long war with Philippine troops, liberated Marawi lies in ruins and its people seethe.
