There is a “huge risk of terrorist attacks in the European Union” over the coming holiday season, a senior EU official has said.

European Home Affairs Commission Ylva Johansson said the polarisation in society caused by the Israel-Hamas war was increasing the risk of violence.

Her remarks came days after a tourist was fatally stabbed in Paris.

The EU was making an additional €30m (£26m) available for additional security, Ms Johansson said.

She did not specify whether there was any specific information which had led to the warning.

“We saw it recently in Paris, unfortunately we have seen it earlier as well,” she added ahead of a meeting of EU interior ministers.
