Nasa leader Raila Odinga on Friday vowed to lead a memorial for those killed by police on the same day that President Uhuru Kenyatta will be sworn into office.
Mr Odinga said Tuesday will not be a celebration day for many Kenyans as the country “will be mourning.”
“It will be crazy for any government to arrange for any ceremony when the country is mourning. There should be no celebration at all,” Mr Odinga spoke at a fund raising event to help meet funeral expenses of those who were killed between November 17 and 21.
“As they will be celebrating, we will be holding a major memorial service at Jacaranda in Embakasi to pray with families of those killed,” Mr Odinga said.
He was accompanied by fellow Nasa principals Musalia Mudavadi and Moses Wetangula and at least 40 Nasa legislators.
He has accused the government of instituting state-sponsored police killings and use of force to repulse supporters who turned out to receive him from his 10-day tour of the US last week.
Earlier, the coalition took a full-page newspaper advert to mourn 26 people it said were victims of police brutality and called on well-wishers to support their families.
