Kenya's opposition has warned it will hold mass rallies if a regional meeting on the post-poll crisis goes ahead.
The Orange Democratic Movement says it was not consulted about the gathering which could undermine talks being chaired by ex-UN chief Kofi Annan.
Previous ODM protests have turned violent and Mr Annan says they are not to go ahead during the negotiations.
Nearly 1,000 Kenyans have been killed and some 300,000 displaced since December's disputed elections.

Nearly 1,000 Kenyans have been killed and some 300,000 displaced since December's disputed elections.
ODM leader Raila Odinga believes he was cheated of victory by President Mwai Kibaki.
'Back-door endorsement'
ODM secretary Anyang Nyongo issued the threat as foreign ministers arrived for Thursday's meeting of the East African regional group, Igad. President Kibaki is the current Igad chair and Mr Nyongo said its meeting would be a back-door endorsement of his presidency and would jeopardise the spirit of the peace talks.
Officials say the ministers are on a fact-finding mission agreed on the sidelines of last week's African Union summit in Ethiopia.
"If the meeting goes ahead as planned we shall mobilise our supporters for a peaceful demonstration against President Kibaki's government," Mr Nyongo warned.
Mr Annan sought to ally ODM's fears saying Igad had nothing to do with his negotiations.
"All parties must avoid provocative statements touching on the matters in discussion," he said.
A framework for the negotiations was agreed last Friday including what caused the political crisis and issues relating to land distribution and historical injustices.
Mr Annan has also called for a South Africa-style truth and reconciliation committee to investigate the political and ethnic violence.
Meanwhile, heads of the tourist business have gathered in the capital, Nairobi to devise a strategy to minimise the damage to their industry.
Revenue has been cut by an estimated $80m (£40m).
But experts say the tourist business could recover quite quickly if there is a political solution which ends the violence and unrest affecting the Rift Valley and Western Kenya.
