Kenyan police has killed 11 people in a crackdown on protesters as anger at the re-election of President Uhuru Kenyatta erupted in the western city of Kisumu and slums ringing the capital.

Speaking with Reuters, a security official said that the bodies of nine young men shot dead overnight in Nairobi’s Mathare slum had been brought to the city morgue.

The official said the men were killed during police anti-looting operations. The run-down neighborhood is loyal to 72-year-old opposition leader Raila Odinga, whose party rejected Tuesday’s vote as a ‘charade’.

A Reuters reporter in Kisumu, centre of post-election ethnic violence a decade ago in which 1,200 people died nationwide, said tear gas and live rounds were fired.

A government official said one man had been killed.

The unrest began moments after Kenya’s election commission announced late on Friday that Kenyatta, 55, had secured a second five-year term in office.

Interior Minister Fred Matiang’i said the trouble was localised and blamed it on ”criminal elements” rather than legitimate political protest.

Odinga’s NASA coalition provided no evidence for its rejection of the result.

Kenya’s main monitoring group, ELOG, said on Saturday its tally matched the official outcome, undermining NASA’s allegations of fraud.

In addition to the deaths, Kisumu’s main hospital was treating four people for gunshot wounds and six who had been beaten by Kenyan police, its records showed.

More shooting was heard outside the hospital on Saturday morning. In Nairobi, armed police units backed by water cannon moved through the rubble-strewn streets of Kibera, another pro-Odinga slum.

Interior minister Matiang’i defended the police against accusations of 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,” Matiang’i added.
