Nairobi — Clashes erupted in a Nairobi slum on Sunday after four bodies were found in the streets, hiking tensions on the eve of a Supreme Court ruling on the validity of last month’s divisive election re-run.

The bodies of three men and a woman were found in the city’s Mathare slum, one of several flashpoint areas where violence erupted during the disputed Oct. 26 vote which was largely boycotted by the opposition.

The discovery came just two days after three people were shot dead in a nearby suburb during clashes with police which erupted as thousands of opposition supporters turned out for their leader, Raila Odinga.

Nairobi police chief Japheth Koome said that the cause of death was not immediately clear but that the victims appeared to have been hit by a blunt object, while one had also been cut.

“Investigations are going on into the killings of the four people in Mathare Area 1,” he said.

“The people were found dead and we want to establish how they were killed,” he said.

“We could see they have been hit by a blunt object, (and) one is cut.”

When the bodies were found, angry residents clashed with police, setting fire to two buses and another vehicle.

In a bid to head off any further unrest, police immediately brought in reinforcements and several water cannon, witnesses at the scene said.

Speaking on condition of anonymity, a police official said that angry residents believed the murders were ethnically motivated, blaming the violence on the Mungiki, a feared criminal gang known for running protection rackets and violently defending tribal business interests.

Drawing its members from Kenya’s largest tribe — the Kikuyu, to which President Uhuru Kenyatta belongs — the Mungiki were responsible for much of the deadly ethnic violence which swept the country in the months after the 2007 election.

Today, the term is widely used in reference to groups of armed Kikuyu men.

But the police chief was quick to rule out any ethnic factors in Mathare, where many Kikuyu live alongside ethnic Luo or Luhya, who largely back Odinga.

“It is not about ethnic clashes,” Koome said, insisting that it was a criminal matter, but without giving details.

Since Friday, Kenya has been on edge following a mass opposition demonstration to welcome Odinga back from a trip overseas turned violent, with three demonstrators shot dead in Muthurwa, a suburb not far from Mathare.

Angry protesters hurled stones at police who hit back with tear gas and water cannon in running street battles which lasted all day.

The violence soured a gathering which had sought to welcome Odinga back from a 10-day trip to the United States where he was trying to rally support for the holding of new elections.

Tensions are also high ahead of a key Supreme Court ruling on Monday over whether Kenyatta can be sworn in for a second term or if there must be another presidential re-run.

Although Kenyatta won the Oct. 26 vote with 98 percent of the votes cast, the ballot was boycotted by Odinga and his supporters who clashed violently with police in his strongholds in the west and in several Nairobi slums.

It was also marred by low turnout.

The vote was the chaotic climax of two months of political drama sparked by an earlier Supreme Court ruling on Sept. 1 which overturned Kenyatta’s victory in an initial August election over widespread irregularities and mismanagement by the IEBC electoral commission.

This time, two legal challenges have been filed over the October election, with Chief Justice David Maraga saying the six-judge bench would hand down its decision on Monday.

If the judges validate Kenyatta’s win, he will be invested on November 28. Otherwise a third election will have to be organized within 60 days. — AFP
