A Supreme Court prosecutor in Greece has ordered that 35 immigrant strawberry pickers, most of whom were injured in a shooting last week, will be awarded state protection as victims of human trafficking.

Twenty-eight migrant workers, mostly from Bangladesh, were injured in southern Greece after foremen allegedly opened fire with shotguns on a crowd demanding six months' unpaid wages.

Supreme Court Prosecutor Ioannis Tentes on Monday ordered that the workers be awarded status as trafficking victims, effectively imposing an indefinite ban on their possible deportation.

Three foremen, Greek men aged 21, 27 and 39, have been charged with attempted murder and illegal weapons possession and will await trial in prison custody.
