Mayor: Car bomb kills 4 in Cali

— The mayor of Cali says a car bomb has exploded in front of the palace of justice, killing at least four people and injuring 20 others.

Jorge Ivan Ospina said the car exploded after it was left outside the palace, which was damaged.

Victims were pedestrians in the center of the city about 186 miles southwest Bogota.

"It has been an attack, a terrorist attack because civilians have died," the mayor told radio station Caracol.

Authorities are investigating the attack and weighing a possible reward for information leading to the attackers.

Diana Salamanca, Cali's interior secretary, told Caracol there was a police officer among the people injured.
