Caracas - Venezuelan authorities were investigating Monday an explosion in front of a mercantile court and congressional offices in Venezuela's capital. The blast caused some damage but no casualties and was the third explosion in Caracas in a week.
The unknown Grupo Venceremos de la Izquierda Central Unida (We Will Prevail Group of the United Central Left) claimed responsibility for the two previous attacks.
The low-intensity bomb on the Jose Maria Vargas building damaged some doors and windows.
Last week, another blast struck the seat of the Vatican's diplomatic mission in Caracas. There was graffiti on the building's walls and leaflets were left at the site.
A day before there was a blast at the statue of United States' revolutionary hero and first elected president George Washington at a square in western Caracas.
