The Presidential election in the Democratic Republic of Congo, due to take place on Sunday has been postponed until March in three areas.
The three areas are Beni and Butembo in eastern North Kivu Province and Yumbi in the west of the country.
The electoral commission blamed insecurity and an Ebola outbreak.
The decision appears to cancel the votes of more than a million people because the new president is due to be sworn in by the middle of January.
An opposition candidate, Martin Fayulu, earlier said any postponement will be an attempt to rig the election.
Mr Kabila, who has been in office since 2001, was meant to have stepped down in 2016 under a constitutional prohibition from seeking an additional term.
However, the election to choose his successor has been continually postponed, amid unrest and reported logistical difficulties.
