Osama planned to get terrorists out of Waziristan
The fear of the remote-controlled killing machines kept al Qaeda militants looking at the sky most of the daylight.
Washington: Dogged by American drone strikes, slain terror mastermind Osama bin Laden had planned getting most of al Qaeda terrorists out of Waziristan, the lawless frontier along the Pakistan-Afghanistan border, according to his seized letters made public.
The fear of the remote-controlled killing machines kept al Qaeda militants looking at the sky most of the daylight, the letter said.
"The brothers who can keep a low profile and take the necessary precautions should stay, but move to new houses on a cloudy day" when visibility for US drones is reduced, bin Laden wrote.
He also encouraged al Qaeda`s leaders to stay far from their troops to reduce the likelihood of being killed.
According to Long War Journal, which keeps tabs on the CIA-operated drone strikes, so far nearly 296 attacks have been carried out leading to killing of approximately between 1,492 to 2,300 militants since 2003.
