It seems that Osama has been in hiding at Barad-dûr.
A post on a mailing list I follow directed my attention to an article at the PakTribune:
[S]ources said that all arrangements had been finalised for a massive offensive against the militants hiding in the Mehsud-populated areas of South Waziristan and in this regard thousands of fresh Pakistan Army contingents were taken to Razmak in North Waziristan who, at any time, could enter the nearby Makin area.
According to military spokesman Maj Gen Athar Abbas, from 50 to 60 militants were killed near Ladha Fort while 20 to 30 militants were killed in fighting near Chagmalai. Maj Gen Abbas said dozens of militants moved to Ladha Fort at 10 am on Friday and attacked the military base. Only small arms and rockets were used in the attack, he added.
I did not create the map, I swear.
