Security forces clashed with about 200 militants from the Moro National Liberation Front for a second day in the southern port city of Zamboanga in Mindanao. At least four people have been killed, and some 180 civilians are being used as human shields by the militants. The city has been put on lockdown as residents have fled the fighting; over 1,000 troops have been called in, and the government is trying to negotiate a resolution. The clash began before dawn yesterday when the militants stormed the city after battling with Philippine naval forces in the port.
