The current security situation in Nigeria, President Muhammadu Buhari, in an interview says, is “very, very disturbing”.

Buhari on Friday acknowledged Nigeria security problems saying developments were sad. He said “What is coming up in the northwest and north central is very, very disturbing indeed.

“I believe the military, the police and other law enforcement agencies, from the reports I am getting, I think they could do much better,” he said on national TV.

“They could do much better, but we are keeping them on the alert all the time to do their duties.”

Is Nigeria safe? Four people were killed late Thursday when rockets slammed into Maiduguri, the main town of Borno state, where Boko Haram first emerged.

Why is Nigeria dangerous? Conflict of a different kind has gripped the northwest and north-central of the country, hitting the states of Zamfara, Kaduna, Sokoto and Katsina.

Here criminal gangs have spread terror in rural areas, stealing cattle, carrying out ransom kidnappings and carrying out ruthless raids on villages.

They are not deemed to have an ideological motive, although some commentators have warned that they could link up with jihadists, noting an ambush in Katsina that killed at least 23 troops.

Is Nigeria security system effective? Last week, the Senate passed a resolution calling for military chiefs to resign or be fired over the country’s “deteriorating security situation”.

The house also asked for an official investigation after a newspaper reported that 356 soldiers had asked “for voluntary retirement” early this month because of poor conditions and high risks.
