Farc leader Timochenko new top target in Colombia

The Colombian leader will now be counting on Venezuela to help capture the leader of the Farc guerrillas, Rodrigo Londoño, alias "Timochenko" following the arrest of one of Colombia's most-wanted men, Maximiliano Bonilla Orozco.

Colombian President Juan Manuel Santos praised his Venezuelan counterpart, Hugo Chavez, for the arrest.

The news came on a visit to Caracas by President Santos , as he and President Chavez cemented their rapprochement after years of mistrust between the neighbours.
