Theme park 'among terror targets' for suspects arrested in France

A theme park in the Paris area was apparently among the targets listed by terror suspects arrested in France over the weekend.

French media is reporting an attack was also planned at an area described as having a "high number of police officers".

The seven suspects - of French, Moroccan and Afghan origin and aged between 29 and 38 - were detained in the southern port city of Marseilles and the eastern city of Strasbourg overnight on Saturday and Sunday, after an eight-month investigation.

Two have since been released.

Police say guns and jihadist propaganda were found during the raids.

The US State Department issued a travel alert on Monday advising US nationals to exercise caution at holiday festivals, events and outdoor markets in Europe in the coming weeks.
