Fighting continues in southern Philippines

Philippine forces launched air strikes on Monday, Sept. 16. 2013 to root out rogue Muslim rebels from a southern city, stepping up efforts to end more than a week of clashes that have killed scores of people.

The fighting has been a stark reminder that decades-old grievances fester in the Catholic-majority country despite strong economic growth and an agreement with the biggest Muslim rebel group that was meant to pave the way to peace. (Reuters)
