NAIROBI, Kenya (CNN) -- The death toll from post-election violence in Kenya climbed to more than 1,000 Tuesday as government and opposition politicians discussed plans that could eventually lead to a power-sharing agreement.
The two sides resumed talks on Monday. Former U.N. Secretary-General Kofi Annan, who is in Kenya to oversee efforts to resolve the crisis, was meeting with senior business leaders on Tuesday, a government spokesman said.
Peace efforts took a hit Monday as South African businessman Cyril Ramaphosa withdrew as the chief negotiator after the government expressed reservations about him. He was instrumental in talks to end apartheid in his own country.
He told The Associated Press he could not function as mediator "without the complete confidence of both parties."
A spokesman for Annan said he had "reluctantly accepted" Ramaphosa's withdrawal.
The latest discussions came as violence across Kenya pushed the death toll to more than 1,000, according to the Kenyan Red Cross.
At least 140 people have died since Friday when leaders of the opposition Orange Democratic Movement reached an agreement with the government to stem the violence that has taken on ethnic overtones.
As many as 350,000 people have been driven from their homes in bloody street battles that have broken out between supporters of President Mwai Kibaki -- a member of the Kikuyu tribe -- and opposition leader Raila Odinga, who belongs to the Luo tribe
Following late December elections, Odinaga accused Kibaki of rigging the vote to win re-election, sparking the breakdown in civil order.
In the midst of the violence, the government faces new difficulties -- finding a way to get migrant workers back to their ancestral homelands, a senior U.N. official told CNN. Ethnic violence is forcing minority tribal members to flee, putting a strain on an already disrupted transportation system.
The quickly approaching rainy season could also add to a brewing humanitarian crisis if farmers -- sidetracked by the violence -- can't get their crops in before the rains come.
On Sunday, the opposition party asked the United Nations and the African Union to send in peacekeepers.
Odinga requested the peacekeepers during a meeting with Secretary-General Ban Ki-Moon at the African Union summit in Addis Ababa, Ethiopia.
"The level of violence in Kenya is unprecedented. It's on a terrifying scale and it has not really diminished," Salim Lone, spokesman for the Orange Democratic Movement, told CNN from London.
"People who have lived together for generations have, after the fraudulent election, turned on each other," he said.
"The security forces seem incapable of stopping this carnage, and in some cases, they actually stand by while the killing goes on," Lone said. "For sure, international assistance is needed." E-mail to a friend
