Nokia reports loss for end of 2011

Mobile phone giant Nokia has reported a loss for the final three months of last year, as sales of mobile devices fell sharply.

The firm made an operating loss of 954m euros ($1.25bn: £800m). Net sales fell 21% on a year earlier to 10bn euros.

Net sales of mobile phones were down by a quarter.

In October, Nokia launched its first two Windows-based smartphones which it hopes will help it gain ground on Apple and Android-based competitors.
