Terrorist Attack Detroit

According to US media, the White House has issued a warning regarding another international terrorist attack like 9/11. According to the reports a terrorist wanted to blow up a flight by setting an explosive device in a flight of Amsterdam flying to Detroit. There are suspects on this case but who are also passengers in the said plane but still investigations are done.

Why are still there are people who are not satisfied of killing their brothers and sisters? What do they need and what makes them happy? I am very much disappointed with this people and I just hope that they will stop and make things right. Please don't attack the community .
