As illustrated in an article by Steve Watson at PrisonPlanet.com, the two Al-Qaeda leaders claimed to have been killed on Monday, actually were claimed to have been captured and killed many times before.
Try to remember the names of the two 'top Al-Qaeda leaders' who they claim were killed. One is called Abu Ayyub al-Masri, the other is called Abu Omar al-Baghdadi. And remember that they are supposed to have been both killed a couple days ago in a raid or airstrike (it's not clear which) on Saturday as you can see from this UPI article for example.
First let's look at Abu Omar al-Baghdadi. Read in this TimesOnline article about how he was claimed to have been captured a year ago. In the same article mention is made of previous claims that he had been killed. So now we are back to having killed him again. Will he rise from the dead once more to be killed or captured when some positive news is needed on the war front?
If that wasn't bad enough, there is also a Reuters article where a U.S. General is quoted as saying Al-Baghdadi doesn't even exist. In fact, according to the general, he was created by the other 'terrorist' just killed, Al-Masri. The general is quoted in the article as saying "Masri had co-founded a "virtual organization in cyberspace called the Islamic State of Iraq in 2006 as a new Iraqi pseudonym for AQI. To further this myth, Masri created a fictional head of the Islamic State of Iraq known as Abu Omar al-Baghdadi."
Now let's look at the other one, the one the general says is real, Abu Ayyub al-Masri. In another TimesOnline article we can read about how he also was captured two years ago, and killed once before that.
