Congo's election commission has set new presidential and legislative elections for December 23, 2018, though the opposition has said it would only agree to delay the vote until June 2018.
As reported by Reuters, government officials have demanded that Internet services be cut off in response to protests on Sunday planned by activists which are demanding that President Joseph Kabila does not change the country's constitution in order to stand for a third term.
The protests have resulted in the death of at least seven citizens, according to the UN.
Human Rights Watch Central Africa director Ida Sawyer said Congolese security forces shot dead two men outside St. Alphonse church in the Matete district.
"The Secretary-General calls on the Government and national security forces to exercise restraint and to uphold the rights of the Congolese people to the freedom of speech and peaceful assembly", said the statement. On Sunday, a United Nations source said eight were killed and 123 arrested, including priests.
The United States has reacted to political ongoings in the Democratic Republic of Congo (DRC) expressing concern at what it said was disproportionate use of force by security agencies.
The UN peacekeeping mission, deployed in 1999 to monitor a cease-fire in a long-running war in the east, is the world's largest, with about 18,000 uniformed personnel. He said the other two deaths occurred during an altercation and would be investigated.
The influential Catholic Church and opposition groups on Sunday pushed ahead with banned demonstrations, which were met with a deadly crackdown by authorities. He said a police officer also died. Across Kinshasa, police and soldiers searched vehicles and checked passengers' identifications.
Speaking to the publication, Telecommunications Minister Emery Okundji said the decision was rooted in "state security" and "the government has the duty to take all measures to protect Congolese lives".
On Sunday, he had said three civilians - "robbers" and "looters" - had been killed, in incidents that had occurred far from the protests.
Congo's President Joseph Kabila addresses the nation at Palais du Peuple in Kinshasa, Congo in April 2017.
More than 160 churches participated in the call.
Some 40 per cent of Congo's population is Roman Catholic and the church, which has mediated in the dispute with Kabila, enjoys some public support, even though its leadership has not formally backed the protests.
