LONDON—The British government does not yet know who was behind Friday's global cyber attack that disrupted the country's health system, interior minister Amber Rudd said on Saturday.
"We're not able to tell you who's behind the attack. That work is still ongoing," she told BBC radio.
She said Britain's National Cyber Security Centre was working with the country's health service to ensure the attack was contained, while the National Crime Agency was working with them to find out where it came from.
