Indonesia arrests 12 suspected militants

JAKARTA, Indonesia (CNN) - Indonesian police have arrested 12 suspected militants who were planning to attack an area frequented by tourists, authorities said Thursday.

The arrests foiled a plot to bomb a cafe in Bukittinggi, a city in West Sumatra that's popular with tourists, said police spokesman Abubakar Nathaprawira.

Authorities also seized a large cache of explosives, including bomb-making materials and guns, Nathaprawira said. The bombs that were being constructed were highly sophisticated, police sources said.
