BOGOTA (AFP) - A car bomb exploded near the mayor's office in the Colombian port city of Buenaventura on Wednesday, killing at least six people and injuring 23 others, local authorities said.
"There are six dead, after one of the injured died," said a spokesman for the ombudsman's office in Buenaventura. Officials said the blast occurred at around 9:30 am local time (1430 GMT).
Army General Freddy Padilla blamed leftist rebels with the Revolutionary Armed Forces of Colombia (FARC).
"Surely this was the FARC," Padilla said.
Defense Minister Gabriel Silva, who traveled to the town in Valle del Cauca state for a meeting on security issues following the blast, said that "all scenarios are evaluated by intelligence (agents)."
The explosion was powerful enough to shatter windows in nearby buildings and carve a hole in the street.
Among the injured there were four seriously hurt, Caracol television reported.
One of Colombia's poorest cities, Buenaventura, some 550 kilometers (340 miles) from Bogota, faces daily challenges from rebels, drug traffickers and other criminals.
