Some demonstrators have staged a counter protest backing the Independent National Electoral Commission outside the National Collation Centre in Abuja.
The protesters are showing their support metres away from another group which is denouncing INEC, accusing the body of running a non-transparent election.
The pro- INEC demonstrators were also carrying placards, one urges Nigerians to stand up for democracy, another advises INEC to complete its job as tension rises over the results.
