KINSHASA, Congo (AP) -- On the eve of the first expected results of Congo's long-delayed presidential election, U.S. President Donald Trump said military personnel had deployed to the region for possible "violent demonstrations," while the country's powerful Catholic church warned of a popular "uprising" if untrue results are announced.
Congo faces what could be its first democratic, peaceful transfer of power since independence from Belgium in 1960, but election observers and the opposition have raised numerous concerns about voting irregularities as the country chooses a successor to longtime President Joseph Kabila.
The first results are expected on Sunday, and the United States and the African Union, among others, have urged Congo to release results that reflect the true will of the people. The U.S. has threatened sanctions against those who undermine the democratic process. Western election observers were not invited to watch the vote.
The Catholic church, an influential voice in the heavily Catholic nation, caused surprise on Thursday by announcing that data reported by its 40,000 election observers deployed in all polling stations show a clear winner. As regulations say only the electoral commission can announce election results, the church did not announce a name.
The electoral commission responded by saying the church's announcement could incite an "uprising."
Congo's ruling party, which backs Kabila's preferred candidate Emmanuel Ramazani Shadary, called the church's attitude "irresponsible and anarchist."
Leading opposition candidate Martin Fayulu, a businessman and lawmaker who has accused Congolese authorities of impeding his campaign, has not commented.
At stake is a vast country rich in the minerals that power the world's mobile phones and laptops, yet desperately underdeveloped. Some 40 million people were registered to vote, though at the last minute some 1 million voters were barred as the electoral commission cited a deadly Ebola virus outbreak. Critics said that undermines the election's credibility.
The Catholic church's letter, seen by The Associated Press, dismisses the electoral commission's accusation that it acted illegally by making its earlier statement, saying its goal is to "make the electoral process credible" and stabilize the country.
The Dec. 30 election took place more than two years behind schedule, while a court ruled that Kabila could stay in office until the vote was held. The delay led to sometimes deadly protests as authorities cracked down, and Shadary is now under European Union sanctions for his role in the crackdown as interior minister at the time.
Kabila, who took office in 2001 after his father was assassinated, is barred from serving three consecutive terms but has hinted that he could run again in 2023. That has led many Congolese to suspect that he will rule from the shadows if Shadary takes office.
With potential unrest a concern, internet and text messaging services were cut off the day after the election in an apparent attempt by Congolese authorities to calm speculation. The United States has urged that internet service be restored, and a United Nations human rights spokeswoman has warned that "these efforts to silence dissent could backfire considerably when the results are announced."
The outages have slowed the transmission of election data, and the release of the first results could be delayed.
While Congo has been largely calm on and after election day, Trump's letter to House Speaker Nancy Pelosi said about 80 military personnel and "appropriate combat equipment" had deployed to nearby Gabon to support the security of U.S. citizens and staffers and diplomatic facilities.
More military personnel will deploy as needed to Gabon, Congo or neighboring Republic of Congo, Trump's letter said.
