Nigeria — A US Embassy cable released by the WikiLeaks website said Nigeria's new president claimed the oil-rich nation's previous president was "in a semi-comatose state" before his death.The cable, released Wednesday night, recounted a conversation between then-US Ambassador Robin Renee Sanders and then-Nigerian Vice President Goodluck Jonathan. The cable claimed Jonathan told the ambassador President Umaru Yar'Adua was semi-comatose "without an understanding of what (was) going on around him."Yar'Adua left Nigeria in November 2009, sparking a constitutional crisis. Jonathan reluctantly took power in February after the National Assembly took an extraconstitutional vote making him acting president.Yar'Adua died May 5. Jonathan was sworn in the following day.
