Police say a powerful explosion near a major Colombian radio station has injured at least four people, according to AP. Bogota police director Cesar Pinzon says investigators suspect a car bomb exploded near Caracol radio. But he says officials have few details so far about the 5:30 a.m. (1030 GMT) blast in the northern part of Colombia's capital. The explosion has shattered windows and damaged the facade of the radio station's building. But the station has continued to broadcast.
