Hello every one, I'd like to say something about Osama Bin Laden. They said in the news that he has been killed four weeks ago. Many people think he was not killed just now, but he's been dead for more than five years. Do you think Osama Bin Laden is the head of Al-Qaeda? Thinking back to 9 September 2001, do you think Osama Bin Laden did that? They said they executed him so, where is his body then?

Can you tell me who is Al-Qaeda?
