Nope. There are zero mentions of Somalia, Mogadishu or the African Confederation in any episode, aside from a single (blink and you'll miss it) shot in TNG: Cause and Effect that wasn't easily readable until the blu-ray was released.
Geordi goes to Mogadishu in the TNG novel Losing the Peace. We learn that he considers it his hometown and that he grew up there, before joining Starfleet.
Geordi La Forge turned his face up to the equatorial sun high
overhead, letting its warmth wash over him. There were still a few
weeks left until the rainy season came to this part of the African
Confederation, and it was significantly warmer than he was used to on
the Enterprise. But he couldn’t very well complain about that.
Because, after all…he was home.
From his vantage point atop the metal bleachers bordering the Zefram
Cochrane High School athletic field, he could see the Mogadishu
skyline to the southeast and—by virtue of his cybernetic optical
implants—the Indian Ocean beyond. Old-fashioned sailboats drifted
lazily on the blue waters that lapped against the pristine white
beaches along the Somalian coast. It was hard to believe the city had
been largely destroyed in the years between the second and third world
wars, and abandoned to rival militias. The ancient port city
experienced a renaissance in the late twenty-second century, and was
rebuilt in a manner that reflected its long history as a major trade
center, using the most modern architectural techniques. It may not
have been Paris or San Francisco, but it was as pristine and perfect a
city as any other on the paradisiacal world called Earth.
And on the field, he was watching the Cochrane Flyers face off against
their crosstown rivals, the Mogadishu Central High Scorpions. The
school band played as, all around him, the other spectators shouted
encouragement to the players or chatted among themselves about nothing
in particular. All of a sudden, the entire crowd jumped to its feet
and exploded in a mighty roaring cheer. Geordi stood up a second later
and saw the Flyers celebrating what must have been an impressive goal.
