Car bomb damages home in southwestern Colombia

A car bomb near a police station in southwestern Colombia has damaged about 200 homes and injured three people. The site is far from where President Barack Obama and other leaders are meeting at the Summit of the Americas.

The explosion in Morales in Cauca province is the fourth since leaders began arriving Friday, but appears unrelated to the summit in the northern city of Cartagena.

Cauca secretary of government Milena Cabeza says the bomb damaged 180 to 200 homes. Three people were slightly wounded but no one was killed.

Authorities did not say who was behind the blast, but various armed groups operate in the area, including the Revolutionary Armed Forces of Colombia and the National Liberation Army.

Two small bombs detonated Friday in Cartagena and one in Bogota.
