To snaking queues of jerry cans.... Nigerians are trying to stock up on fuel.

In Lagos, Dorcas Sunday has been waiting here overnight -- and then some.

''I have been here since yesterday morning to buy fuel," she says.

The panic buying is being fed by uncertainty over the end of Nigeria's fuel subsidy.

New President Bola Tinubu vowed to scrap it a few days ago.

And on Wednesday, the NNPC - Nigeria's state oil firm - hiked petrol prices as high as $1.21 a liter from about 40 cents.

The price increase could lead to higher transport fares...

...and hurt businesses that rely on petrol generators...

All in a country where many consider cheap petrol a right.

In the capital, Abuja... people endured similar gridlock to get it.

Cynthia Patrick manages a fleet of buses and has spent several hours in line.

"Look at all the cars and buses parked here..."

Africa's most populous nation and biggest oil exporter is grappling with feeble growth, high inflation and falling oil production due to crude theft and underinvestment.

The last time the government tried to remove the subsidy, in 2012, there were nationwide protests.

The NNPC says the popular but costly benefit costs close to $900 million every month.

On Wednesday it said prices were being adjusted, quote, "in line with the current market realities."
