Thousands of Nigerians rally a week before crucial vote

The frontrunners in Nigeria's presidential candidates hit the campaign trail on Saturday, in a major push to convince voters a week before the polls.

More than 90 million people are registered to vote in Nigeria where President Muhammadu Buhari is stepping down after his two terms allowed by the constitution.

Waving from the top of an open-air double-decker bus, the ruling party's candidate Bola Tinubu of the All Progressives Congress (APC) paraded through the streets of Maiduguri in northeast Borno state.

Tinubu was expected to stage a final rally in Lagos on Tuesday.

In nearby Adamawa state, the main opposition's candidate Atiku Abubakar of the Peoples Democratic Party (PDP) also made an entrance in the city of Yola on a double-decker bus.

Thousands of people attended both rallies, waving flags and shouting party slogans while loudspeakers blasted music.

Outsider candidate Peter Obi was not seen on the campaign trail but took to social media to call on his supporters, "the Obidients", to rally in several cities across the country.

In the capital Abuja, several hundred Obi supporters marched from the centre to the city gate, chanting and blowing vuvuzuelas.

Campaigning is taking place as the nation faces widespread insecurity and tensions over a currency crisis.

On Saturday morning, gunmen attacked a police station in the Ogidi area of southeastern Anambra state.

"The hoodlums started shooting sporadically on approaching the area command and threw improvised explosive devices and petrol bombs, gaining entrance (into the station)," police spokesman Ikenga Tochukwu said in a statement.
