Who is responsible
The Irish government has warned it is a "likely coordinated campaign of disruption." Irish Prime Minister Micheál Martin described the situation as "worrying" and said his government’s first priority was the safety of the Irish public. Martin told RTÉ it was not yet known if the threats had come from individuals or if it was a "coordinated attack."
The Russian extremist group "Male State", named in this week’s hoax bomb threats to Italian airports, denied any link to the false warnings. Replying to the BBC Russian Service, an account on Telegram linked to the group said: "What Male State? Where have you seen it? It hasn’t existed for many years."
The European Commission announced the activation of an information exchange mechanism among EU member states in light of the sequence of incidents, and it said it was still early to determine whether they are related.
