Democratic Republic of Congo faced growing pressure from African neighbours and beyond on Monday for a recount of its contested presidential election in a dispute that threatens more violence in the volatile nation.
The 30 December vote was supposed to herald Congos first democratic transfer of power in six decades of independence and a new era after president Joseph Kabilas chaotic 18-year rule.
But monitoring groups noted widespread irregularities including faulty voting machines and poorly run polling stations, overshadowing talk of democratic progress in the vast country of 80 million people.
Second-place finisher, former Exxon Mobil executive Martin Fayulu, says he in fact won by a landslide with over 60 per cent of votes and that the official winner, opposition leader Felix Tshisekedi, struck a deal with Kabila to be declared the victor.
Tshisekedi and Kabila deny this.
The International Conference of the Great Lakes Region (ICGLR), a 12-member body including Kinshasa allies Angola and Republic of Congo, expressed "great concern".
"We suggest that the competent structures consider counting the votes in order to guarantee the transparency of the results," it added in a statement.
Pressure on Kabila has built since the vote, in part because Congos influential Catholic Church said tallies by its 40,000-strong monitoring team show a different winner to that announced by the electoral commission.
France, Belgium, the United States and Britain have all expressed concern. But perceived criticism from inside Africa could hold greater sway, with approval from regional partners critical for the legitimacy of president-elect Tshisekedi.
The CIRGL statement late on Sunday echoed the Southern African Development Community (SADC), which contains allies of Kinshasa like South Africa and Angola.
However, some regional powers remain wary of interfering in Congo in case it stokes violence or influences the result. In separate statements on Monday, South Africa and Zambia both softened their tone and said they would not push for a recount.
Congo government spokesman Lambert Mende told Reuters it was up to the Constitutional Court to decide on a recount.
"It is not up to an organisation, a foreign state, to tell a judge how to draw his own conclusions," he told Reuters. "Recounting the votes is a verification technique that only a judge can decide."
Fayulu has gone to the court alleging fraud and the Catholic Church has also weighed in.
"We recommend that (electoral commission) CENI recount votes to reassure all stakeholders," said Donatien Nshole, secretary general of Congos Catholic bishops conference.
Isolated post-election violence in Congo has many fearing a return to the kind of conflict and upheaval that killed millions since the 1990s and destabilised the region.
Congo is the worlds leading miner of cobalt, a mineral used in electric car batteries and mobile phones, and Africas biggest copper producer. It also mines gold and diamonds.
But unrest, disorganisation and corruption has left many in poverty, dissatisfied with Kabilas rule.
Armed groups roam Congos eastern border with Uganda and Rwanda, hobbling efforts to contain an Ebola outbreak that has killed nearly 400 people.
The government cancelled the election because of insecurity in these eastern opposition strongholds and in the northwestern town of Yumbi where unrest broke out.
Clashes between Batende and Banunu ethnic groups in and around Yumbi killed over 400 people over two days in December, a local priest and a civil society activist told Reuters on Monday, a death toll three times higher than earlier estimates.
The fighting on 16-17 December was some of the worst to hit the normally peaceful area in years. Some of the surrounding villages remain deserted after hundreds fled across the Congo River into Congo Republic, the sources said.
