Recently, a Malaysian state of Sabah have seen an incursion by an armed group originated from Southern Philipines and claiming to be the Royal Army of Sulu. They've landed on the shore of the Sabah province of Lahad Datu on 9th February 2013. Here's the chronology of events for those who miss it.

By today the conflict have escalated to the Province of Semporna and the casualty have increase to 12 dead on Malaysian side and probabaly 20 or so on the Sulu side.
I wish to ask any knowledgable people here. According to Geneva Convention, how should we deal with this incursion?
