DR Congo got their Group D campaign at the African Nations Championship (CHAN) off to a winning start as they beat 10-man Mauritania 1-0 in South Africa.
The winners of the first CHAN in 2009 beat the debutants, thanks to a 51st-minute penalty by Eddy Emomo.
Emomo sent Mauritania keeper Brahim Souleymane the wrong way following a Mohamed Wade foul on Firmin Mubele.
Both opening group matches were played in Polokwane, with the other game - between Gabon and Burundi - ending 0-0.
Mauritania played the final 15 minutes with 10 men after captain Moussa Baghayoko was booked for a second time.
Earlier, DR Congo coach Santos Muntubile was banished to the stands.
He was sent off for haranguing the assistant referee when a penalty claim for handball was turned down in the 20th minute.
Seven minutes before half-time, DR Congo were unlucky not to take the lead when Guy Lusadisu headed against the post.
Moments later at the other end Joel Kimwaki cleared a Ely Cheikh Voulany effort off the line with DR Congo's Robert Kidiaba beaten.
In the later game, Nguema Obame missed the best chance to win the match for Gabon.
He failed to direct a header on goal after Burundi goalkeeper Arthur Arakaza came off his line and misjudged a cross.
Substitute Samson Mbingui then thought he had given Gabon a late winner, but his header was ruled offside as the points were shared.
