Four people have been killed, including a six-month-old baby and a police officer, after a gunman opened fire at a Roma camp in France.

The three civilians who died were all members of the same family and also included the baby's mother and grandfather.

The woman's three-year-old child was also seriously wounded when the attacker shot the victims in a caravan.

Police said the suspect was then shot and injured by police.

They had responded to the call at the camp in the northern town of Roye.
