DATU SALIBO: The Philippines’ largest Muslim militant group has launched a deadly offensive against a splinter faction that has pledged allegiance to the Islamic State group, police said Saturday. The fighting between the two groups began about two weeks ago in the marshy farmlands around the southern town of Datu Salibo on Mindanao island, regional police spokeswoman Tara Leah Cuyco said.
