A cyber strike which hit dozens of British hospitals on Friday is part of a wider "international attack", Prime Minister Theresa May said.
"We are aware that a number of NHS organisations have reported that they have suffered from a ransomware attack. This is not targeted at the NHS, it's an international attack and a number of countries and organisations have been affected," May said, referring to the country's National Health Service.
The NHS declared a "major incident" after the cyber attacks, which prompted some hospitals to divert ambulances and scrap operations.
