Gabon's President Ali Bongo has returned to Morocco to continue his rehabilitation, a government source told Reuters news agency.
It is less than 48 hours after he returned to the Gabonese capital Libreville.
Mr Bongo returned Gabon on Tuesday - just over a week after an attempted coup - ahead of a ceremony where a new cabinet was sworn in.
While he was still in Gabon, he was pictured at the swearing-in:
Mr Bongo, who has been out of the country for two months, reportedly suffered a stroke in October and received treatment in Morocco.
He sought to put an end to the rumours about his health with a televised New Year message in which he said he was feeling fine.
Soldiers said they had been disappointed by the message, calling it "a pitiful sight" and a "relentless attempt to cling onto power."
