Around 300 inmates are on the run after a suspected raid by Islamist Boko Haram militants on a prison in Nigeria's capital Abuja on Tuesday night, an interior ministry official said.
The raid, and a separate ambush on an advance convoy of Nigerian President Muhammadu Buhari - who was not present - heading to his hometown in the northern state of Katsina, highlights Nigeria's going security challenges, especially in northern regions where armed insurgents and gangs are rife.
