Update: Death toll of Philippines massacre reaches at least 46

A police official says 11 more bodies have been unearthed from a mass grave in the southern Philippines, bringing the death toll from a massacre of political supporters and journalists to 46. Police Chief Superintendent Josefino Cataluna says 11 bodies were recovered before sundown Tuesday from a hillside grave. Eleven other victims were discovered there earlier in the day.

Police said a convoy of about 40 people was going to register Ismael Mangudadatu, vice mayor of Buluan township, Monday to run for provincial governor when they were stopped by about 100 gunmen. Soldiers and police found 24 bullet-riddled bodies Monday including those of Mangudadatu's wife Genalyn and his two sisters.

Previously, Philippine President Gloria Macapagal Arroyo placed two southern provinces under a state of emergency. The emergency measures, including checkpoints and random searches by authorities, will remain in place until the president is confident that law and order have been restored in the region
