Talks are entering their second and last day in the Zambian capital, Lusaka, to try to find a solution to the conflict in the Democratic Republic of Congo.

Representatives from Central and Southern African nations are meeting amid signs that prospects for a political settlement remain far-off.

Delegates supporting the Congolese government's position said that a sticking point was the refusal of Rwanda and Uganda to acknowledge they were directly supporting rebels in eastern Congo.

A rebel delegation in Lusaka -- earlier kept in a separate building -- has been allowed into the hotel where the meeting is taking place but has not entered the conference hall; Zambian officials were acting as intermediaries.

Zimbabwe, Angola and Namibia have deployed troops in Congo in support of President Kabila.

South Africa has called for a diplomatic solution.
