Paris police find bomb-making kit

French police have discovered bomb-making material in a car park linked to the weekend arrests of a dozen terror suspects, the state prosecutor said today.

Francois Molins said the material was found in a suburb east of Paris.

Twelve people were arrested last weekend over the firebombing of a kosher grocery store north of the capital last month.

Mr Molins said the detention of the suspects will be extended for 24 hours.
