Paris attack survivor: 'It was a bloodbath'

France has declared a national state of emergency and tightened borders after at least 128 people were killed in a night of gun and bomb attacks in Paris.

The targets included bars, restaurants, a concert and a high-profile football match.

Amélie, a survivor of the mass shooting at the Bataclan concert hall in Paris, has described hiding from the gunmen as they fired on others.

''It was a bloodbath, it was slaughter, dead people everywhere,'' she said.
