Two bombs explode in Colombia

At least four people were injured in Colombia after two car bombs exploded.

One bomb went off near a military barracks in the Caribbean resort of Cartagena; the other exploded in a residential area of Medellin.

Police say they do not know who planted the bombs.

Correspondents say pamphlets were found near the site of the explosion in Cartagena criticising the recent decision by Congress to allow the extradition of Colombians to face charges abroad.
