Bomb threats disrupt flights across Europe

Airlines across the continent have been affected by threats, now in their second week, with some planes making emergency landings or being escorted by fighter jets. The countries affected, including Spain, France, Ireland and Bulgaria, haven't established who is behind the threats, but aviation experts say they are likely coordinated. It comes as parts of Europe face increasing "hybrid attacks": last month, temperature systems for fridges and freezers in supermarkets across the continent were hacked, destroying millions of dollars of food.
