Ivory Coast qualify as Senegal eliminated
Missiles, stones, bottles and firecrackers were thrown on to the pitch by disgruntled home fans, who were frustrated with their team's poor show that left them trailing 2-0 when the match was halted.
Both teams had to be escorted out of the grounds by security forces, who fired tear gas inside the packed stadium to stop the rioting.
"CAF decided to officially confirm the result of the match as 2-0 in favor of Ivory Coast in accordance with the... the regulations of the competition and to consider Senegal the loser of the said match and eliminated from the competition without prejudice to any other sanctions that may be imposed by CAF Disciplinary Board," the Confederation of African Football (CAF)said in a statement on its website.
CAF rules state that: "If the referee is forced to stop the match before the end of the regular time because of invasion of the field or aggression against the visiting team, the host team shall be considered loser and shall be eliminated from the competition."
The Africa Cup of Nations will be held from January 19 to February 10 in South Africa.
