AFP - At least two people were killed and several others injured when a bomb blast shook an upscale northern Bogota neighborhood late Tuesday, said city official Clara Lopez.
The explosion rocked the La Cabrera neighborhood around 0200 GMT causing destruction in a 100-meter (yard) radius, an AFP journalist reported.
"Unfortunately, there are two people dead and several wounded," Lopez told reporters.
The blast caused the first floor of a two-story building to collapse, shattering windows and trapping several parked cars under rubble, although witnesses said the cars were empty.
Lopez appealed for calm. "The authorities are already at the site investigating the scene," she said, calling on citizens to help.
"We heard a very loud blast. The windows were shattered. So we went out into the street and we saw three people wounded who were then taken away by an ambulance," said Maria Teresa Burbano, who works at a business close by.
"The blast was very strong. Several of my colleagues fell to the ground," said Javier, an employee of the Club Colombia restaurant in the area who declined to give his last name.
The previous attack that shook Bogota lightly wounded five people on December 29. Police attributed the attack to guerrillas with the Revolutionary Armed Forces of Colombia (FARC).
Sixteen people were injured when six low-impact explosive devices were set off on October 23. The authors of the attack have not yet been identified.
Between June and October 2008, six other improvised device explosions took place in the capital.
