'The new Abu Tubar had unique and different nom de guerre, Abu Deraa, Father of the Armor, a reference to his penchant for attacking U.S. armored vehicles. He is known of having a big amusement in torturing his victims who most of them are Sunni civilians. One of his signature techniques is running a drill into the skull of his live victim, according to a recent Time article. His appetite for mayhem is so vast that some Iraqis call him the "Shiite Zarqawi"'
'After going far in his crimes, Abu Deraa became hated even by some of his cleric leaders. Iraq for All, an Iraqi local news website reported that Muqtada al-Sadr himself dismissed 60 members, including Abu Deraa, from the Mahdi Army militia. However, the man was still considered a hero, especially by Shiite members in the parliament.
Falah Shansal, a member of parliament from the al-Sadr bloc, told Time last week that Abu Deraa was still "a fighter in the Mahdi Army."
Like most of the “wanted” insurgents, Abu Deraa was hard to be caught. He managed to escape several times until he was killed few days ago by a Sunni insurgent group. Azzaman newspaper reported that the Islamic Army, one of the insurgent armed groups, killed Abu Deraa.'
