unfire was also heard in the second city, Lubumbashi, but it was unclear who was behind the shooting.

In a video posted on social media, main opposition leader Etienne Tshisekedi called for peaceful protests to demand Mr Kabila’s resignation.

“I launch a solemn appeal to the Congolese people to not recognise the… illegal and illegitimate authority of Joseph Kabila and to peacefully resist [his] coup d’etat,” Mr Tshisekedi said.

His message was not available in DR Congo, where authorities have restricted access to social media networks, the AFP news agency reports.

DR Congo has not had a smooth transfer of power since independence from Belgium in 1960.

Mr Kabila took power in 2001 following the assassination of his father Laurent Kabila.

The constitution bars him from seeking a third term in office.
