Webo's brace maintained the Lions' perfect record in Group 5
Cameroon maintained their perfect record in Group Five of the 2008 Nations Cup qualifiers after a 3-1 victory over Liberia in Yaounde on Saturday.
The Indomitable Lions have nine points, three more than Equatorial Guinea who moved second when beating Rwanda 3-1 in Malabo on Sunday.
Equatorial Guinea's policy of recruiting Spain-based players paid dividends as they inflicted Rwanda's third defeat in as many qualifiers.
Juan Anderson opened the scoring after 10 minutes and Rwanda briefly rallied as Olivier Karikesi levelled the scores seven minutes later.
In an incident-packed first half, Samuel Rondo converted a 25th-minute penalty and Alfonso Epitie grabbed the third and deciding goal after 83 minutes.
In Yaounde on Saturday, a brace by Spain-based striker Achille Webo gave Cameroon their third win in as many matches.
Webo opened the scoring with an easy tap-in 12 minutes into the tie after the Liberian goalkeeper failed to handle a cross from fellow forward Samuel Eto'o.
Osasuna striker Webo doubled the Lions' lead in the 24th minute, but the visitors pulled one back through Greece-based striker Francis Doe seven minutes before half-time.
Cameroon wrapped up both the points and the scoring with four minutes remaining when Mahamadou Idrissou scored his third of the qualifying campaign.
The second half had proved a lacklustre affair with both sides squandering chances and passing poorly.
Cameroon's interim coach Jules Nyongha even substituted three-time Caf African Footballer of the Year Samuel Eto'o after an hour following a disappointing display from the Barcelona man.
The visitors were undone by defender George Gebro, who received his marching orders for a second bookable offence, and the home side duly took advantage as Idrissou sealed the win.
Cameroon will play Liberia in Monrovia in the the next round of qualifiers in June.
