In Group H, Namibia were unable to make their first-half chances count during their home game against Tunisia in neutral Johannesburg,
However, the North Africans could count themselves somewhat fortunate when Charles Hambira’s 14th-minute effort was ruled out after Erastus Kalula was adjudged to have fouled goalkeeper Bechir Ben Said.
The draw takes Namibia on to eight points in Group H, two behind Tunisia, while Liberia are a point further back after Sheikh Sesay’s last-minute winner gave the Lone Stars a 1-0 away win against Sao Tome e Principe in neutral Oudja, Morocco.
However, the picture is complicated by Fifa’s ruling that Emilio Nsue was ineligible to play for Equatorial Guinea in their first two qualifiers – which turned their 1-0 wins over Namibia and Liberia into 3-0 defeats.
The Central Africans could yet appeal the sanction.
Elsewhere, Djibouti picked up their first point in Group A with a 1-1 draw against Ethiopia, who remain fifth in a table topped by Egypt.
