Celebrations, otherwise somberCelebrating Tshisekedi supporters converged on his party headquarters in Kinshasa, DR Congo's capital, where the mood was otherwise reported to be largely somber amid memories of elections in 2006 and 2011 that were marred by bloodshed.
"This is the coronation of a lifetime," said Rubens Mikindo, deputy secretary-general of Tshisedeki's party, the Union for Democracy and Social Progress (UDPS).
Tshisekedi, 55, pledged to work closely with Kabila.
"Today we should no longer see him as an adversary, but rather as a partner for democratic change in our country," Tshisekedi said.
Result 'opposite to what we expected,' says Le DrianFrench Foreign Minister Jean-Yves Le Drian said the surprise result was the "opposite to what we expected," based on field observations of the December 30 vote that was marred by voting machine malfunctions and Ebola virus outbreaks.
Belgian Foreign Minister Didier Reynders said Thursday that Belgium, Congo's former colonial ruler, would use its temporary UN Security Council seat to "find out what's going on."

Results 'negotiated,' says Fayulu"These results have nothing to do with the truth at the ballot box," Fayulu told Radio France International.
"How long are we going to negotiate results?" asked Fayulu. "In 2006, Jean-Pierre Bemba's victory was stolen. In 2011, Etienne Tshesekedi's victory was stolen. In 2018, victory won't be stolen from Martin Fayulu."
Third-placed on 23.8 percent, Emmanuel Ramazani Shadary, Kabila's preferred successor, congratulated Tshisekedi through a spokesperson, saying his win represented the "will of the people."
Avoid speculation, urges South Africa's RamaphosaSouth African President Cyril Ramaphosa urged the international community to refrain from speculation and congratulated Congo on its election outcome.

Backroom deal?Sasha Lezhnev, deputy director of the Africa-focused Enough Project, said: "if it looks like the vote was rigged and that Kabila is actually staying in power via a backroom deal, then sanctions and other financial pressure should ensue."
