Greek cities hit by fresh rioting

Five demonstrations are planned in major cities later, including a mass rally by the Communist Party in Athens, where Saturday's shooting occurred.

Two police officers have been arrested in connection with the boy's death. One of them, who is accused of murder, said he fired a warning shot and that the boy was killed by a ricochet, but witnesses told Greek television that the officer aimed directly at the boy.

The second officer has been charged with being an accomplice.

A post-mortem is being carried out on the body of Alexandros Grigoropoulos, which should help to determine the trajectory of the bullet. The boy's family has hired an independent pathologist to ensure there is no cover-up.
