Spyker Cars NV, the Dutch parent of Saab, said the Swedish automaker's financial situation is worsening and warned that Saab's future is at risk without additional financing.

Earlier this week, Saab was forced to shut down production for short intervals after key suppliers halted parts deliveries for non-payment.
