Along the Chari and Logone rivers separating Cameroon from Chad's capital, four flat-bottomed boats, mounted with machine guns, brimming with Chadian and other special forces, round the curve as they approach the riverbank.

Forming an assault force, heavily armed soldiers leap out of the vessels and race up a slope to take up positions while backup forces have their machine guns at the ready.

Marie-Victoire Carvalho Sow is busy in the annex to her kitchen in Dakar, dishing out giant ladles full of a traditional Senegalese Easter treat.

It's called ngalakh – a delectable mix of millet, groundnut (peanut) paste, bouye (the fruit of the baobab tree, which is also known locally as pain de singe or monkey bread), sugar, vanilla essence and orange blossom.

She says every year, Catholics make this special food for Good Friday and it's savored over Easter weekend.

It's been more than a month since Nigeria's president, Muhammadu Buhari, traveled to London on what was billed as two weeks' vacation — with routine medical check-ups. He hasn't been back home since.

His government says the 74-year-old is in good health. But many Nigerians are not convinced and wonder whether their president is gravely ill — or worse.

Buhari's long absence comes amid Nigeria's worst economic crisis in years and other pressing national problems, including a famine in the northeast, the region badly hit by extremist Boko Haram violence.

A prominent Muslim leader in Nigeria is making a point about a common practice in Islam. He says if people are worried about poverty or terrorism, they should consider how those problems can be made worse by polygamy. Here's NPR's Ofeibea Quist-Arcton.

President Robert Mugabe turns 93 on Tuesday, making him the oldest president in Africa — and the world. He's the only leader most Zimbabweans have ever known, spending nearly 37 years at the helm since independence from Britain and the end of white minority rule in Rhodesia in April 1980.
