(IsraelNN.com) Germany is in shock following the arrest of a Muslim who planned to bomb commuter trains, and Chancellor Angela Markel stated Monday that the country must begin using video cameras and other means to track down terrorists. Interior Minister Wolfgang Schaeuble said in an interview on German public television that he fears attacks by Muslims who were raised in the country. "We don't know anymore who is living among us."Most European countries, including Germany, have become a breeding ground for Muslim terrorists born and raised in the countries, which gives them the right to citizenship. One of the hijackers involved in the 2001 attacks on the United States is Saudi national Mohamed Atta who studied in Germany and belonged to an Al Qaeda cell in Hamburg.
