The killing of Al-Qaeda leader Al-Zawahiri brings closure to families of the nearly 3,000 victims of the 2001 attacks but it has raised several questions. There are questions about the route the US drone used in the attack and the mystery behind the remains of Al-Zawahiri.

Did US drone use Pakistani airspace for Al-Zawahiri killing?

On 30th July, a US drone strike sealed the fate of Al-Qaeda chief Ayman Al-Zawahiri, killing him in Kabul, Afghanistan. It's been four days since the strike but neither the US nor the Taliban have come out with any material evidence of the Al-Qaeda chief's deaths.

Al-Qaeda leader and Bin Laden's successor Ayman Al-Zawahiri had a 25 million dollar US bounty on his head and was obviously in hiding but the Taliban takeover of Afghanistan changed that. Zawahiri apparently felt comfortable enough to move to Kabul living in a house and it was here that a US drone strike sealed his fate.
