About 15 passenger planes were forced to land in European countries after receiving reports of the presence of bombs on board, amid a security alert and extensive investigations. Reports include trips to Belgium, France, Italy, Czech Republic, Bulgaria, Romania and Poland. IP European authorities are investigating the possibility that the reports are related to each other and that they are part of "hybrid attacks", while no dangerous substances were found in some of the planes that were inspected.
