Officals in Tunisia say that at least 34 African migrants - including babies and children - are missing after their boat capsized off the Tunisian city of Sfax.

It's the fifth such shipwreck in the past two days.

A total of 67 people have been reported missing.

Tunisian officials say there's been a sharp rise in boats carrying would-be migrants towards Italy.

The coast guard has reportedly also stopped more than 50 boats leaving in the past two days.

A Nigerian producer, now artist, has told the BBC that the success of the Afrobeats music genre has only just started.

"I feel like we're just starting. We're not even there yet. Give us time," Otaniyen-Uwa Daniel said.

"For me, my measure of success is that I want to hear the songs in Mexico, in China and Korea, everywhere. Everyone knows reggae music. I want people to listen to us like that," he continued.

Killertunes was born in Benin City and has gone on to produce top artists such as Wizkid, Mr Eazi, and his mentor Timaya.

His production skills are also self-taught: "Back then in Benin there was no internet, to go on YouTube. I didn't even know there was something like YouTube where I could learn to produce."

His first big hit came when he was producing for Timaya on a track called I Concur.

He says on his current project he is blending RnB with jazz and is particularly excited about an as-yet unreleased track he has recorded with Patoranking and Davido.

"Whenever that song drops, trust me... it's over!"

The Chadian government has nationalised assets belonging to a subsidiary of Exxon Mobil.

It’s the latest development in a dispute between the authorities of the Central African country and the US oil giant over the sale of its assets in Chad to a third party.

The vast majority of Chad’s revenue comes from exporting oil. So when it disagreed with the terms under which Exxon sold its Chadian assets to British company Savannah Energy last year, it promised to go to court to block the purchase.

Now the Chadian authorities have gone one step further - they’ve nationalised Exxon’s assets, a move which could potentially spook foreign investors.

Savannah Energy has said it will challenge the move legally. The assets involved include a 40% stake in Chad’s Doba oil project - seven oilfields with a combined output of 28,000 barrels per day.
