Workers at a failed French car parts supplier are threatening to blow up their factory unless the company's two biggest clients - Renault and PSA Peugeot -Citroën - stump up extra compensation.

Employees of the engine parts maker New Fabris have rigged up gas canisters inside a factory workshop, which they say will be detonated on July 31 if the two carmakers fail to pay €30,000 (£26,000) to each of the 366 workers facing unemployment.
