Kenya's Gor Mahia and Rwanda's Rayon Sport increased their Confederation Cup points tally to two each after their second successive draws against USM Alger and Yanga respectively on Wednesday.
A 10-man Gor Mahia held the Algerian side 0-0 in their Group D encounter at the Kasarani stadium in Nairobi, while the Rayon Sport and Yanga clash finished goalless in Dar es Salaam.
The results leave USM Alger atop the group with four points, having beaten Yanga 4-0 in their first group match in Algeria. Yanga remain the Group D tail-enders with a single point so far.
Gor Mahia had Joash Onyango red-carded in the 55th for a second bookable offence.
In Group B, Morocco's Renaissance Berkane secured a 2-0 victory over hosts UD Songo of Mozambique, thanks to Ayoub El Kaabi's double strike.
Played the final
The goals further staked El Kaabi's claim for a place in Morocco's final World Cup squad due next month in Russia.
In the other match in the group, Sudan's Al Hilal were held to a 1-1 draw by visiting Egypt's Al Masry, who took the lead after just 10 minutes through Islam Issa.
Hosts Hilal, who played the final 65 minutes with 10 men after the dismissal El Tahir Hassan, equalised when Brazilian Geovane Maranhao converted an 82nd minute penalty.
Berkane top Group B with six points, Masry are on four, Al Hilal have just one, while Songo are pointless.
