At least 158 inmates escaped a jail in the southern Philippines after an attack by gunmen early Wednesday morning. Armed police stand guard at the gate of the jail.

Armed police patrolled along the perimeter fence of the jail and it is reported that at least one jail guard was killed during a two-hour long fire fight with over 100 armed men.

Jail officials inspected the perimeter fence of the jail, and one official said the facility houses 1,511 inmates including some “high profile” inmates belonging to the Bangsamoro Islamic Freedom Fighters rebel group operating in central Mindanao.
