The first explosion hit a market and the second a densely populated neighbourhood, both in the capital of Cameroon’s Far North region, Maroua, a military source told Reuters.
According to reports, the two suicide bombers were two women with bombs attached to their bodies.
However, it wasn’t clear whether the women were willing suicide bombers or were forced to do so by Boko Haram.
No one claimed responsibility, but Boko Haram has stepped up attacks on the countries bordering its northeast Nigerian stronghold – Chad, Niger as well as Cameroon.
“People were running in all directions,” said Celestin, a teacher, who said he had just arrived at the city’s central market when the first bomb went off.
Reuters’ television images showed the market littered with debris as military and health officials removed corpses from the scene wrapped in sheets.
