Two terrorist attacks on the Kenyan coast was not orchestrated by the al Shabaab terrorist network, according to the country's president Uhuru Kenyatta.
Mr Kenyatta said the 65 people were killed by "local political networks", dismissing claims by Somalia's al Shabaab Islamist group that it was behind the assaults.
Speaking to the nation, he said:
"This was not an al Shabaab terrorist attack. Evidence indicates local political networks were involved in the planning and execution of the heinous crime.
"This also played into the opportunist network of other criminal gangs," he said.
The Kenyan president Uhuru Kenyatta has tweeted his condolences to Nelson Mandela's family and friends:
Kenya's chief justice said that the six-member Supreme Court had taken a unanimous decision that Uhuru Kenyatta was validly elected president, after the result was challenged by defeated candidate Raila Odinga.
"It is the decision that the third and fourth respondents were validly elected," Chief Justice Willy Mutunga said in court, referring to Kenyatta and his running mate and deputy president William Ruto.
