Memorial held for Arizona shooting

President Obama has honoured the victims of Saturday's shooting in Arizona urging Americans to heal the divisions caused by what he called the 'sharply polarised' political debate.

Six people were killed and 13 injured in the attack.

Congresswoman Gabrielle Giffords is still critically ill but doctors said she was making good progress.

Hundreds attended the funeral of a 9-year-old girl who died in the shooting.
