Ivory Coast President Alassane Ouattara has announced he will run for a fourth term in October's election.

In a statement, the 83-year-old said his health was not an issue and his candidacy was driven by a need to "preserve national stability amid ongoing security and economic challenges".

Ouattara argues a new constitution approved in 2016 reset his two-term limit, meaning he is allowed to stand.

He will be the poll's frontrunner, as several potential challengers have already been barred from the race.

The excluded candidates include former President Laurent Gbagbo, ex-Prime Minister Guillaume Soro, and former minister Tidjane Thiam.
