The International Transport Workers' Foundation (ITF) is speaking out following the shooting of the leader of its dockers union in Argentina.

The labour group said on Tuesday that it "condemns in the strongest possible terms" the attempted killing of Roberto Coria, who was standing for re-election as secretary general of the Sindicato de Guincheros.

"This was a heinous and cowardly act," said ITF president and dockers chair Paddy Crumlin.
