Here is a look at some of the places hit by the global cyberattack.

European Union — Europol’s European Cybercrime Center, known as EC3, said the attack “is at an unprecedented level and will require a complex international investigation to identify the culprits.”

Britain — Britain’s home secretary said the “ransomware” attack hit one in five of 248 National Health Service groups, forcing hospitals to cancel or delay treatments for thousands of patients — even some with serious aliments like cancer.

Germany — The national railway said Saturday departure and arrival display screens at its train stations were affected, but there was no impact on actual train services. Deutsche Bahn said it deployed extra staff to help customers.

Russia — Two security firms — Kaspersky Lab and Avast — said Russia was hit hardest by the attack. The Russian Interior Ministry, which runs the country’s police, confirmed it was among those that fell victim to the “ransomware,” which typically flashes a message demanding payment to release the user’s data. Spokeswoman Irina Volk was quoted by the Interfax news agency Saturday as saying the problem had been “localized” and that no information was compromised. Russia’s health ministry said its attacks were “effectively repelled.”

United States — In the U.S., FedEx Corp. reported that its Windows computers were `”experiencing interference” from malware, but wouldn’t say if it had been hit by ransomware. Other impacts in the U.S. were not readily apparent.

Turkey — The head of Turkey’s Information and Communication Technologies Authority or BTK says the nation was among those affected by the ransomware attack. Omer Fatih Sayan said the country’s cyber security center is continuing operations against the malicious software.

France — French carmaker Renault’s assembly plant in Slovenia halted production after it was targeted. Radio Slovenia said Saturday the Revoz factory in the southeastern town of Novo Mesto stopped working Friday evening to stop the malware from spreading.

Brazil — The South American nation’s social security system had to disconnect its computers and cancel public access. The state-owned oil company Petrobras and Brazil’s Foreign Ministry also disconnected computers as a precautionary measure, and court systems went down, too.

Spain — The attack hit Spain’s Telefonica, a global broadband and telecommunications company.
