Denmark's Defence Intelligence Service warned on Sept. 24 that Russia will intensify hybrid attacks on Europe in the coming months, including destructive cyberattacks and sabotage carrying a higher risk of casualties, adding that it sees a low but growing risk of a limited Russian military attack on NATO's eastern members even during the Ukraine war. Separately, El Mundo reported on Sept. 23 that U.S. intelligence warned Spain, France and Italy of a possible Russian drone attack from shadow fleet vessels in the Mediterranean, which Italy's defense minister dismissed.
