More than 40 million T-Mobile customers have been hit by a US data breach, the company has admitted.

It blamed the breach on a "highly sophisticated cyberattack".

It said it is "taking immediate steps to help protect all of the individuals who may be at risk from this cyberattack".

The firm said that while criminals stole personal information, no financial details were leaked as a result.
