A government soldier takes a position with a machinegun at the porch of a house during fighting with Muslim rebels from the Moro National Liberation Front (MNLF) in Zamboanga city, southern Philippines, September 15, 2013. A week of violence in the southern Philippines has undercut hopes of lasting peace in the resource-rich region and exposed the government to criticism for underestimating rogue Muslim rebels who feel ignored by a landmark deal last year.

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)
