Gunman shoots policeman in Athens
A Greek riot policeman has been seriously injured by a man with a submachine gun in central Athens, officials say, BBC reported.
The officer was part of a unit guarding the culture ministry when the pre-dawn attack took place.
The policeman was rushed to hospital and was due to be operated on.
A huge manhunt is under way. Last month Greece saw its worst riots in decades after the fatal shooting by police of a teenager in Athens.
