The United States has cautioned Americans to reconsider travelling to or across Nigeria.

The caution followed the Friday killing of Iranian General Qassem Soleimani in a drone airstrike ordered by President Donald Trump.

The US Embassy in Nigeria, in a statement on its website, admonished American citizens to review their personal security measures, be prudent and keep a low profile.

Stating that it had no specific security threat information, the mission advised US nationals in Nigeria to stay alert in public places, including schools, hospitals, government facilities, places of worship, tourist locations, and transportation hubs.

Security Expert, retired Col. Hassan Stan-Labo said the security alert from the US is in order.

Already, the Inspector-General of Police, Mohammed Adamu has placed Police Commands and Formations nationwide on red alert.

The Presidency has said that President Muhammadu Buhari will not manipulate the process to pick a successor ahead of the 2023 Presidential elections.

The response follows a call by the Senior Pastor of the Latter Rain Assembly, Tunde Bakare, who urged the president to be involved in the choice of his successor in order not destroy his legacies.

Speaking on a monitored programme, Special Adviser to the President on Media and Publicity, Femi Adesina, stressed that contrary to call, President Buhari will ensure that the process is free, fair and credible.

He added that though the president is interested in who would succeed him, but will not pick a successor.

Adesina also stressed that the president will ensure that his successor builds on the gains of his administration and will not allow looters to find their way to power.
