BOGOTA, Jan 27 (Reuters) - A bomb exploded in Colombia's capital late on Tuesday, killing two people and wounding 20, police said.

Police and emergency workers cordoned off the area after the explosion was felt in a northern part of Bogota.

Bombings have been rare in the capital since President Alvaro Uribe cracked down on leftist rebels fighting a four-decade war against the government.

Police did not immediately blame any group for the explosion.
