Security measures will be costly for western countries.

French President Francois Hollande’s increased spending to boost security in the wake of the deadly attacks in Paris should be given special treatment under Europe’s budget rules, European Commission President Jean-Claude Juncker said.

“We are faced with terrorist acts. France and other countries need additional means and these additional means should not be dealt with on the same footing as regular spending,” Juncker told an audience in Brussels on Wednesday.

Following the assaults in the French capital that killed at least 129 people on Nov. 13, Hollande said he is ready to breach the European Union’s budget-deficit ceiling to spend whatever is needed to ensure security. He promised more money for intelligence services, additional police officers and no cuts to the army’s personnel numbers.

The European Commission has already said that extra spending by governments to deal with the influx of refugees into the bloc may receive a reprieve under the budget rules, which include an annual deficit limit of 3 percent of gross domestic product.

When nations are faced with “unusual events outside the control of the government,” then spending can be increased without drawing sanctions, the commission said on Nov. 17. While the statement referred to refugee-related spending, Commission Vice President Valdis Dombrovskis said the EU executive would assess the impact of France’s security spending.
