Mobile phone giant Nokia has reported a loss in the final three months of last year, as sales of mobile devices fell sharply.
The Finnish firm announced a loss after tax of 1.08 billion euros.
Sales of the company's new Windows-based smartphones failed to dent the dominance of Apple's iPhone or compensate for diving sales of its own old smartphones.
The company launched its first two Windows-based smartphones in October, dumping its Simbian operating system.
Net sales of mobile phones were down by a quarter.
