Laurent Gbagbo

Mr. Gbagbo is the first former head of state to be tried at the International Criminal Court in The Hague.

The former leader of Ivory Coast will be the first ex-president to be tried by the court when it opens on Thursday.

The provisional results, announced by the Independent Electoral Commission, declared Mr. Ouattara the winner, with 83.7 percent of the vote.

President Alassane Ouattara was set to claim a landslide victory Wednesday after results of weekend voting were released in 19 of 31 regions.

For now, President Alassane Ouattara’s chief challenge is keeping the peace on Election Day, the baseline needed for any future economic gains.

The International Criminal Court said former President Laurent Gbagbo would be tried on charges of crimes against humanity in connection with violence after 2010 elections in Ivory Coast.

Ivory Coast has decided it will not send Simone Gbagbo, the wife of former President Laurent Gbagbo, to the International Criminal Court to stand trial.

The International Criminal Court said in its warrant that Simone Gbagbo, the wife of Laurent Gbagbo, the Ivory Coast strongman, played a central role in postelection violence in 2010 and 2011.

The International Criminal Court said that it would expand its investigation into political violence in Ivory Coast to look into crimes as far back as 2002, soon after Laurent Gbagbo became president.

The elections, in the aftermath of violence after the previous president refused to accept his defeat, are expected to strengthen support for the current one.
