African leaders call on Zibabwe parties to sign deal

JOHANNESBURG, South Africa (CNN) - A summit of regional leaders in South Africa ended Sunday with no agreement to end Zimbabwe's political crisis.

But the leaders said they believe there is a basis for a power-sharing deal, and called on both sides to sign it.

South African President Thabo Mbeki, the lead Zimbabwe negotiator for the 14-member Southern African Development Community (SADC), said the group wants Zimbabwe's government leaders and opposition to "conclude the negotiations ... as a matter of urgency."

"It's clearly not possible to say when negotiations will be concluded," he told reporters after the summit. "It's a matter of negotiating parties reconvening."

SADC did not give a cut-off date, he added.
