A MEXICAN campaigner demanding justice for 43 murdered students has been assassinated.

Miguel Angel Jimenez was found riddled with bullets in a car outside the village of Xaltianguis in Guerrero state over the weekend. His funeral was held there on Sunday.

Mr Jimenez, a member of the Union of Peoples and Organisations of Guerrero (UPOEG), organised search parties for the bodies of 43 teaching students who disappeared in September.
