Italy's PM Silvio Berlusconi is bloodied by attack

Italian Prime Minister Silvio Berlusconi has been hit in the face and knocked to the ground after a political rally in Milan.
Pictures showed Mr Berlusconi, 73, with blood around his mouth and on his face. Reports suggested he had either been punched or hit with an object.
Mr Berlusconi was taken to hospital. A first medical report said two teeth were damaged, with one broken.
A man, who reportedly has a history of mental problems, has been arrested.
After the attack on Sunday evening the prime minister, looking dazed, was helped to his feet by aides and put in a car. He got out and tried to climb on the car to show he was all right, before being driven away.
