Hoax bomb threats against European flights widen to broadcasters and air traffic

A cyberattack on supermarket refrigeration, bomb threats against planes and software vulnerabilities have left Europe on edge, with officials urging resilience and stockpiling. On Friday the string of hoax alerts that has diverted flights this week expanded to newsrooms, and fresh threats were reported against air traffic. Scores of flights have received threats this week, but no explosives have been found so far.

• A Russian extremist group has denied sending the hoax threats to European flights.
• On Thursday bomb threats forced several airliners to land unexpectedly, including an Aer Lingus Dublin to Rome flight diverted to the Évreux military base in France.
• No country has assigned blame for the threats. European officials have accused Russia and Iran of hybrid attacks and sabotage, which both deny.
