Polls close in Nigeria's long anticipated elections

The main opposition Peoples Democratic Party (PDP) has reacted to the elections held in many parts of the country.

Nigerian elections have previously been characterised by voting along ethnic and religious lines.

"What's going on?" asked Buhari's campaign spokesman, Festus Keyamo, saying electoral commission workers arrived at his polling station in Delta state an hour and a half late.

"At this moment we recorded a total point of 92.76% of the polling units that opened", he said.

Preliminary results are expected in about two to four days, according to observers.

Most polling stations closed at 2 p.m local time (1300 UTC) in Nigeria on Saturday following a delayed election to pick the president of Africa's most populous nation and leading oil producer.

He voted in his hometown of Daura, in northwest Nigeria. "I will congratulate myself. I'm going to be the victor", he told reporters.

Buhari scored 523 votes while the Presidential candidate of the PDP, Atiku Abubakar got only 3 votes.

The results - including for a parliamentary election that ran alongside - will be announced in the early part of next week.

Domestic observer Jude Okafor said voting in Yola was peaceful.

He said: "I understand that they didn't start by 8 but I don't know why".

The press officer, EU Election Observation Mission, Sarah Fradgley, said this in a message from Abuja.

The wife of the president looks to have allowed him so to do with the entire episode drawing laughter among the people present at the booth.

Shortly before polls opened, a series of blasts rocked the northeastern city of Maiduguri, which has been repeatedly hit by Boko Haram Islamists.

"And we have to give this message to Nigerian people - to go and vote for the future".

"The government made the decision - in consultation with the security agencies - that it is better and more useful for the security agents, including soldiers, police, Civil Defence, DSS, etc to focus their attention on providing security for the election throughout the state".

"The gunfire was not targeted at members of the public but was for security objective", he added.

Maiduguri is the birthplace of Boko Haram and has been repeatedly attacked during their almost 10-year insurgency that has devastated the remote region.

Nigerians have begun voting in a presidential election one week after a surprise last-minute delay blamed on logistical challenges.

The army also confirmed a "futile" attack on a security outpost in Geidam in Yobe state.

The delay also could hurt the election's credibility, some said.

The early morning explosions in Maiduguri come after a Boko Haram attack late on Friday on Zabarmari village, 10 km outside the city.
