The governor of Colombia's Arauca state has escaped unharmed from a bomb attack on his motorcade.
A government spokesman says explosives planted under a bridge detonated Tuesday as Governor Julio Enrique Acosta Bernal's motorcade passed through Arauca city, the provincial capital. The governor's armored vehicle was heavily damaged but no one was seriously injured.
Governor Acosta Bernal has survived eight attacks during his political career. Authorities in Arauca province say they suspect the latest attempt to kill him could have been staged by rebels from the FARC - the Revolutionary Armed forces of Colombia.
Colombia's main oil fields are located in Arauca state, near the border with Venezuela. Frequent activity by rebels and other criminal gangs has forced the government to keep the area under virtual military control for the past three years.
