Thousands of people have staged a protest in the Burundian capital over a United Nations report that accuses the government of carrying out serious rights abuses.

A group of independent experts on Tuesday called for the creation of an U.N. panel to deepen a probe of "gross human rights violations" in Burundi, pinning most of the blame on President Pierre Nkurunziza's government and its allies.

The protesters Saturday included lawmakers, government officials and ordinary citizens who marched past U.N. offices in Bujumbura.

Violence in the East African nation soared after Nkurunziza's contested decision last year to seek a third term, which critics called unconstitutional.

The experts cited among the abuses as the president sought to stay in power are a "conservative estimate" of 564 executions carried out since April 2015.
