Blackberry to axe thousands of jobs
21 September 2013 Last updated at 22:54 BST
Blackberry has announced it is planning to cut 4,500 jobs, or 40% of its worldwide workforce, in an attempt to staunch huge losses.
The smartphone maker said it anticipated a loss of as much as $995m (£621m) when it reports its second-quarter earnings next week. In August, the Canadian company said it was evaluating a possible sale.
Shares in the firm closed down 17% after briefly being halted following the announcement.
