David Ervin, Australian intelligence chief, said that he suffers from insomnia as he recieved reports about many Australian people go to Africa and the Middle East, especially in Yemen and Somalia, to receive training on terroristic attacks.
He added they are currently managing 200 anti-terrorism operations, but he can't sleep as he knows about those terrorists among the Australian people.
After killing bin Laden, al-Qaeda has become weak, but I can't guarantee to protect Australia against terrorism as long as those terrorists practice violence in the name of jihad and they are convinced that they will enter paradise after blowing themselves!
