Four explosions hit Colombia
Bogota - Four explosive devices went off in Colombia late on Friday ahead of an Americas summit, without causing any casualties or damage to the building, police said.
The first two crude low-power bombs exploded near the US Embassy in Bogota shortly after the arrival in Colombia of US President Barack Obama, who is due to take part at the Americas summit in the resort city of Cartagena.
"Nobody was killed, nobody was injured, and there was no damage," a police official told AFP on condition of anonymity, and without giving any word on the suspects.
These explosions were followed by two similar ones in Cartagena, which is hosting the summit.
"They occurred near a bus terminal and near a supermarket," General Rodolfo Palomino of the Colombian police told reporter. "There were no injuries and no damage."
In addition to the US Embassy, the area in Bogota where the devices exploded is home to some important Colombian government buildings.
