MANILA, Philippines (AP) — The military says at least six people, including two television journalists, were wounded when a home-made bomb exploded on a roadside in the southern Philippines.

The blast early Saturday happened in an area where government troops have been battling Muslim insurgents opposed to a new peace deal.

Regional military spokesman Col. Dickson Hermoso said the victims were hit by shrapnel from the blast in Maguindanao province’s Datu Saudi Ampatuan township. He says there were no serious injuries.

The explosions came three days after troops captured a rebel stronghold with bomb-making and training facilities. They want an independent Islamic state and broke away from the mainstream rebel group.

Hermoso says at least 52 insurgents and one soldier have been killed in the fighting since Monday.
