Burundi's ruling party has bestowed the title of "eternal supreme guide" on President Pierre Nkurunziza, a party official confirmed Sunday.
"He is our elder, our father, our adviser," CNDD-FDD secretary general Evariste Ndayishimiye said in a video sent to AFP whose authenticity was confirmed by an official.
A party statement issued after a meeting Saturday of the party's top leadership in Nkurunziza's native Buye in the north of the former Belgian colony did not spell out the implications of the title.
The 54-year-old former rebel leader has ruled the densely populated central African country since 2005 after a devastating civil war.
A constitutional referendum in May could allow him to run in elections in 2020, paving the way for him to remain in power until 2034.
Critics mocked the development, with one decrying the "cult of personality around his majesty the King Nkurunziza I".
But another party official, who asked not to be named, insisted to AFP the move did not reflect "an excess such as those of (former North Korean dictator) Kim Il Sung, as our detractors suggest".
Burundi has faced a serious political crisis since Nkurunziza sought a fiercely contested third term in office in April 2015.
Post-election violence claimed at least 1,200 lives and displaced more than 400,000 people between April 2015 and May 2017, according to estimates by the International Criminal Court, which has opened an investigation.
Nkurunziza has led several purges in the ranks of the former rebellion and surrounded himself with a select group of generals.
Opposition parties warn the constitutional changes could deal a death blow to the Arusha peace accords that helped to end the 1993-2006 civil war, in which more than 300,000 people died.
The Arusha accords stipulate that no president can govern the country for more than 10 years. The current constitution sets a limit of two five-year mandates.
