The slain Kasipul Member of Parliament Charles Ong'ondo Were was on Wednesday eulogised as a dependable leader.
National Assembly Speaker Moses Wetangula, who urged MPs to subject their security details to fresh vetting, termed the MPs death unfortunate.
The late MPs colleagues spoke when they gathered at Consolata Shrine in Westlands, Nairobi during a requiem mass.
Calls for tighter security for Members of Parliament took centre stage during the mass. Leading MPs and other national leaders during the mass, Wetangula said it was the fourth time that an MP was killed in tragic circumstances.
