Opposition leader Raila Odinga will make a major announcement Tuesday.

Addressing his supporters in Kamukunji, Raila asked his supporters to boycott work.

“We will announce our next cause of action on Tuesday, don’t go to work tomorrow,” said Raila.

James Orengo accused the media of not reporting the truth and asked the supporters to boycott NTV and and Nation newspapers.

Raila had not spoken since them but MPs elected under  Nasa addressed a media conference on Saturday where they asked supporters not to fight with the police.

Police have killed at least 11 people in a crackdown on protests as anger at the re-election of President Kenyatta erupted in Kisumu and slums surrounding the capital.

However, tNASA put the death toll at more than 100, including 10 children, but did not provide evidence. Odinga has rejected the poll and its result as “massive” fraud.

The eruption of violence has revived memories of a decade ago, when Odinga, now 72, lost an election in controversial circumstances that sparked a wave of political and ethnic unrest in which 1,200 people were killed and 600,000 displaced.

Kofi Annan, the former U.N. head who mediated during that crisis, on Saturday issued a statement warning Kenya’s leaders to “be careful with their rhetoric and actions in this tense atmosphere”.

Reuters was able to confirm 11 deaths, including one girl, in the space of 24 hours. The Kenya National Commission on Human Rights said 24 people had been shot dead by police since Tuesday, election day.

Acting Interior Minister Fred Matiang’i had earlier said trouble was localized and blamed it on “criminal elements” rather than legitimate political protest. He also denied accusations of police brutality.

“Let us be honest – there are no demonstrations happening,” he told reporters.

“Individuals or gangs that are looting shops, that want to endanger lives, that are breaking into people’s businesses – those are not demonstrators. They are criminals and we expect police to deal with criminals how criminals should be dealt with.”

Former CJ Willy Mutunga has told off Matiang’i over utterances that only criminal gangs are being dealt with during post-election protests.

Matiang’i who is acting Interior CS denied that live bullets are being used against protesters, saying only criminals were facing the full force of the law.

Mutunga fired back on Twitter saying, “Criminal gangs have rights. Arrest them, charge them in court. State protects the rights of all including the scum of the earth among us.”
