'Nigerians now depend on the black market to survive'

Mark Uma, Abuja, Nigeria

Queue at a fuel station in Nigeria

"The queues at fuel stations are terrible and fuel prices are rising hourly.

Fuel stations get the oil overnight at 1am when people are sleeping.

I don't know how they get it.

There are massive queues in the morning as soon as people wake up.

There is no power at the moment either."

Zoe Idusogie, Lagos, Nigeria

"A lot of people are going behind closed doors to buy fuel.

The prices are not the problem now, it is actually getting the fuel.

It is very difficult to get to work. We have to walk to work, but that's not possible for me as it's too far.

This crisis has been going on for three weeks but has now reached a critical situation"

Mohammed Manko, Abuja, Nigeria

"It's a very terrible situation. Everything in Nigeria is shutting down.

The prices of every commodity are rising. It's been like this for the last couple of weeks.

It's the government's fault. The government should be paying more attention to creating more refineries"

Francis Olumide, Abuja, Nigeria

Francis filmed scenes and took photos of people looking for petrol and and sent them to us via WhatsApp.

Francis Olumide: "We are threatening to call a workers' strike in Nigeria"

"It's a very, very critical situation. I would say a national security crisis.

There is no fuel and no light. I cannot power my business premises now.

We are threatening to call a workers' strike in Nigeria.

Nigerians now depend on the black market to survive.

The illegal gas sellers get constant supply but we have empty gas stations.

I am saving the little diesel for evening when it will be dark."

Nkem Opara in Lagos, Nigeria: The fuel scarcity is so bad in Nigeria and due to a lack of electricity as well, businesses are shutting down, and the rest of the masses are in pitch darkness. I just got emails from Guaranty Trust Bank and Airtel apologising for their inability to carry out normal business operations going forward. Our President GEJ is making no effort to resolve the fuel crisis among other issues, as the country slowly comes to a halt. This might be the worst president we've ever had.
