Former UN Secretary General Kofi Annan and nine former African heads of state have made an urgent appeal for a peaceful democratic transition in the Democratic Republic of Congo.
President Joseph Kabila did not step down when his mandate ran out last year, sparking a political crisis.
Under the terms of an agreement signed on New Year's Eve, elections should take place this year. But Mr Annan and the other African leaders say the deal is not being respected, and as a result the country's future is in grave danger.
