UK hospitals hit by large-scale cyber attack

A large-scale cyber attack has plunged the United Kingdom's health service into chaos.
Computers in hospitals and clinics across the country shut down on Friday (May 12), forcing patients to be turned away.
IT systems and telephone networks appear to have been targeted, with some hospitals now operating on an emergency-only basis.
The "ransomware" computer attack demands $300 per computer in electronic currency in order to free files from encryption.
A message appearing on screens across the National Health Service warns time is running out to make payment.
Patients have reported being turned away, while some are stuck at hospital without access to discharge data.
NHS England have confirmed they are aware of the problem and say they will release details soon.
