Voter registration has started in the capital of the Democratic Republic of Congo, despite a decision to postpone elections until December.
The process could take four months
Polls were due to take place this month as part of the country's peace process.
Dozens of public buildings in Kinshasa have been turned into registration stations and thousands of people are queuing to get their voting cards.
But the opposition is not involved in the registration and has called for protests against the delay.
Opposition parties are also calling for the government to resign.
Fears of violence
It might take at least four months for the estimated 28 million voters to be registered.
It is not clear whether the proposed demonstrations will remain peaceful.
Armed police have increased their presence in Kinshasa's streets.
And many in the Congolese capital fear the process that should bring an end to five years of war in the Congo might be surrounded by further violence.
