As opposition fighters close in on Muammar Gaddafi's compound, speculation is rife about the whereabouts of the Libyan leader himself.  

The US believes he is still in Libya, according to the Pentagon.

Some suggest he could be in neighbouring Algeria, or in remote southern Libya.

Other options could be Angola or Zimbabwe, both close regional allies.
