“No reaction from me, it’s an ongoing trial…,” Ouattara said in an interview with Radio France International in the Ethiopian capital Addis Ababa where he was attending an African Union summit.
But he added: “Someone must be responsible for the 3,000 deaths. I hope that justice will shine a light on that, it is what the victims are asking for.”
ICC judges acquitted Gbagbo and his aide Charles Ble Goude on charges stemming from a wave of violence after disputed elections in the west African nation in 2010.
More than 3,000 people died on both sides of the Ivory Coast conflict after Gbagbo refused to concede defeat to Ouattara, his internationally backed rival.
Gbagbo, the first former head of state to stand trial at the ICC, is currently living in Belgium under conditions pending a possible prosecution appeal following the acquittal on January 15.
He had been held in the Netherlands since 2011.
The ICC’s unwillingness to let Gbagbo return to Ivory Coast is thought to have been linked to the country’s refusal to surrender Gbagbo’s first wife, Simone, despite an outstanding ICC warrant for her arrest for her role in the post-election violence.
She was convicted and jailed by the courts there in 2015, but Ouattara granted her an amnesty last year along with 800 others.
“We are continuing our investigations in order to establish who is responsible (for the deaths),” Ouattara said in the interview to be broadcast Monday.
And he denied that any pressure had been brought to bear on the ICC to prolong the detention or trial of Gbago.
“Interfering with international or national justice, this is not how I manage my country… let justice take its course,” he said, refusing to discuss any possible return of Gbagbo. “Let’s wait and see.”
– ‘No problem’ with Soro’ –
Ouattara also returned to the subject of the resignation of the speaker of the National Assembly, Guillaume Soro, who headed rebel forces during the Ivorian war, and then joined the government under Gbagbo.
Soro is a member of Ouattara’s Rally of Republicans (RDR) and is rumoured to have fallen out with Ouattara and possibly to have his own presidential ambitions.
Ouattara said he believed there were ideological differences between the two but “no problem” between them.
“I’m not a man to force anyone (to resign)… Soro believed that we did not share the same ideology. We are a social liberal party and he considers himself a Marxist. I understand that this is not compatible with his beliefs,” he said, adding: “He is a young man that I consider as one on my sons. I do not rule out that he will return.”
Nor did Ouattara rule out Soro standing for the presidency in 2020.
“It’s his choice, he can do as he wishes. The constitution authorises him to do so and it is not a question of me standing in the way of his candidature….”
Gbagbo’s release has come at a particularly tense time in Ivory Coast.
With presidential elections due next year, Ouattara has not said whether he will seek another term, and the coalition he formed with Henri Konan Bedie, his former ally against Gbagbo, has collapsed.
“It’s very clear, I can run if I want. There’s a new constitution (since 2016),” he said.
“All the legal opinions that I have consulted have confirmed it. I will announce my decision in 2020. I can take a decision up until July 28, 2020,” he said.
