 Complete the following phrase:  Between July and December 2003, TF 121 carried out twelve unsuccessful raids to find Saddam Hussein, together with 600 other operations against targets, including 300 interrogations. On 12 December 2003, a raid on a house in Baghdad, that was being used as an insurgent headquarters, captured Muhammed Ibrahim Omar al-Musslit, who was Saddams right-hand man, known to TF 121 as the source or the fatman. Early the next morning he revealed where Saddam may be found. This intelligence and other intelligence from detained former members of the Baath Party, supported by signals intelligence from the ISA, finally pinpointed Hussein at a remote farm compound south of Tikrit.
