Bomb kills 10 in Columbia

A car bomb has exploded near the Columbian capital, killing at least 10 people and injuring more than 60.

Several buildings were heavily damaged, including the offices of Super Noticias radio station, and cars were wrecked in the blast.

No one has claimed responsibility for the blast in Villavicencio, near Bogota, but police suspect the country's main rebel group.

Authorities have asked local residents to donate blood to hospitals for the wounded.

A tennis complex on the outskirts of the city is the site of Colombia's Davis Cup tennis match this weekend against Uruguay.

There is no news on whether any of the tennis players are among the victims, or whether the tournament will proceed as scheduled.

Colombia's 38-year civil war kills an estimated 3,500 people every year.

Violence has worsened since February, when the Colombian government ended a three-year peace process with the Revolutionary Armed Forces of Colombia, the country's main rebel group.
