New wave of bomb threats hit European airlines

While no link has been established between the threats against airlines and media outlets, the Irish government has warned it is a "likely coordinated campaign of disruption".

In a statement, it said: "Hoax threats such as these cause fear, distress and disruption to people going about their daily lives and activities; they achieve no positive purpose whatsoever. It is not known yet who is responsible for these threats, whether it is individuals or a centralised or co-ordinated effort.

Irish Prime Minister Micheál Martin described the situation as "worrying" and added his government's first priority was the safety of the Irish public.
