The archbishop of Kinshasa is urging peace on the eve of Democratic Republic of Congo's long-delayed presidential election, saying differences of opinion are no reason to "light the country on fire."Archbishop Fridolin Ambongo held a Mass in the capital on Saturday attended by leading opposition candidate Martin Fayulu and a representative of ruling party candidate Emmanuel Ramazani Shadary. They and sole female candidate Marie-Josee Ifoku held hands during prayer in a spirit of reconciliation.The archbishop said "unfortunately, some of our compatriots give the impression they want to hold the country hostage to violence."He also called the decision to bar some 1 million people from voting because of an Ebola outbreak a "denial of justice." They will vote in March, long after DRC's new president is inaugurated. Protests followed the decision.* Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
