Interior CS Kithure Kindiki has warned against the resurgence of the outlawed militia Mungiki and the country's division.
Speaking in ACK Cathedral, Siakago Mbeere North Constituency, Embu County, Kindiki warned leaders against inciting the youth and recruiting them to outlawed groups like Mungiki.
"In the past, the Mt. Kenya region and other parts of our country have suffered deeply from proscribed groupings such as Mungiki. Political leaders who are trying to revive this illegal group will not be allowed or entertained," Kindiki said.
"The Government will not allow the nation to slide back to where it was 20 years ago when Mungiki and other proscribed groups terrorised our country. Any attempts to revive these criminal gangs will be dealt with the same ruthlessness as the fight against banditry or terrorism."
The CS has accused the opposition of inciting disunity in the country by calling for secession, the latest clarion call by Azimio la Umoja-One Kenya coalition party.
"Kenya is a democratic country, but we won't allow anyone to incite or hurt the country's unity and stability. Anyone who tries to hurt the unity and indivisibility of our country must be rejected, whether they are in opposition or not. Being in opposition is not a license to incite disunity," he added.
"Any person or any leader, regardless of their stature or rank, serving or former, elected or not elected, trying to recruit our young people to join proscribed organisations like Mungiki, will be dealt with firmly and in accordance with the law."
Kindiki says the talks about secession are not only dangerous but irresponsible coming from the opposition.
"As the country prepares to celebrate Madaraka Day on Thursday, talk about secession is not only dangerous but irresponsible. Kenya is one United and indivisible country," Kindiki said.
Speaking on Friday during a thanksgiving service at Kalonzo Musyoka's Yatta Farm, Azimio leader Raila said he was going to write to the United Nations to separate from the President William Ruto-led State.
"We will write to the UN for self-determination so that every Kenyan community can feel completely they are part of the government. If you read Kenya Gazette every week, it's only one region. Kenya has 45 communities, all of them are Kenyans and they are paying taxes," Raila said.
Raila was accompanied by former Mungiki leader Maina Njenga, and Narc Kenya leader Martha Karua among other Azimio leaders.
