Group has pledged allegiance to IS, according to officials

Muslim extremists who support the Islamic State group staged a daring jailbreak in the southern Philippines, freeing 23 detainees in the latest in a series of mass escapes, officials said on Sunday.

About 50 heavily armed members of the Maute group raided the local jail in the southern city of Marawi on Mindanao island on Saturday and freed eight comrades who were arrested barely a week ago, police said.
