ZAMBOANGA: Philippine troops are locked in a standoff with hundreds of Muslim gunmen who killed six people and took at least 20 hostages in the south in a bid to derail peace talks.
A night-time curfew was imposed in this southern port city as armoured security forces surrounded between 200 and 300 Moro National Liberation Front (MNLF) gunmen holed up in six coastal villages on its outskirts.
