European election observers have called for an inquiry into the accuracy of Kenya's official presidential election results.
The European Union observer team released its formal assessment of the election Tuesday as police continued efforts to halt post-election violence that has killed at least 150 people.
In a statement, the EU monitors said last week's polls fell short of international standards for democratic elections. It said a lack of transparency in the vote-counting raises concerns about the accuracy of the final results.
Opposition candidate Raila Odinga and his party say the results of last Thursday's election were rigged to make sure incumbent President Mwai Kibaki was the winner.
Tuesday, Kenyan police warned they would not authorize a rally Mr. Odinga has called in Nairobi's Uhuru park on Thursday. Police officials say the rally poses a threat to people's safety and security.
Continued violence was reported Tuesday in Nairobi and other cities. Witnesses in the western city of Kisumu say around 40 bodies were brought into a mortuary overnight.
Much of the violence appears to be ethnically motivated, with members of Mr. Odinga's Luo tribe clashing with the Kikuyu tribe of Mr. Kibaki.
Both Mr. Kibaki and Mr. Odinga have appealed for calm. Western embassies, including those of the United States, Britain, and Australia have warned their citizens to remain vigilant and avoid travel.
