Former President of Bolivia Evo Morales has travelled to Cuba "for health reasons" and will return to Argentina next weekend, Morales' press office reported on Monday.

"Former President Evo Morales undertook an unscheduled journey to Cuba last night for health reasons. His return is scheduled for next weekend in order to fulfill the programmed agenda," a press release said.

Morales had a larynx operation in Cuba in April 2017 in which a benign tumor was removed from his left vocal cord.

Morales' trip was also confirmed by Argentine President Alberto Fernandez.

"So they have told me, and it seems to me that he needed some (medical) treatment and had to travel. I spoke with him a few days ago and he commented on it," Fernandez told Argentina's Radio Continental on Monday.

Morales arrived in Argentina under refugee status on Dec. 12.
