The death of 43-year-old American man Eric Garner has sparked an uproar following the release of a v.
Ivory Coast players and fans were targeted by stones, bottles and chairs hurled by Senegal supporters during Saturday's game at Stade Leopold Sedar Senghor, after the visitors had taken a 2-0 lead for a 6-2 aggregate advantage in a qualifier for the 2013 finals in South Africa.
As fires were set in the stands and missiles rained down, the players - as well as 300 visiting fans - were forced to take refuge in the centre circle, while the security forces used tear gas to quell the rioting fans.
"We are going to face some difficult days but Senegal will accept the sanctions," said former international Coly. "In the meantime, we must apologise to Ivory Coast and make sure we do everything to avoid this happening again.
"I feel great sadness because this type of thing has no place on a football pitch or anywhere else.
"For the players, it was traumatic, especially the young ones. The psychological work needed will be extremely difficult." Senegalese politicians also waded into the controversy on Sunday.
"It's a shame, it's regrettable," said Mbaye Ndiaye, Senegal's interior minister. "But we say bravo to the Ivory Coast team for their achievement, their behaviour, their wisdom, and their sense of fair play."
Trouble broke out in the 60000-capacity stadium after a penalty converted by Ivory Coast captain Didier Drogba 15 minutes from time gave the top-ranked African nation a 2-0 lead.
China-based Drogba, the eldest player in a "golden generation" of Ivorian footballers chasing elusive Nations Cup winners' medals, also scored the opener from a powerfully struck free-kick soon after half-time.
