BLIND Colombian former Farc liberation movement negotiator Seuxis Hernandez, best known as Jesus Santrich, has gone on hunger strike after his surprise arrest yesterday.

A US extradition warrant accuses him of trying to smuggle several tons of cocaine into the US.

More than 100 former guerillas and Farc sympathisers gathered to demand his release late last night outside the heavily guarded prosecutors’ bunker where Mr Santrich is being held.
