A requiem mass is being held for Kenya’s former First Lady Lucy Kibaki, who died last week of an undisclosed illness in London.

Dozens of leaders, including President Uhuru Kenyatta and his deputy William Ruto, are attending the funeral mass, the Daily Nation reports.

Interior Permanent Secretary Karanja Kibicho has told people to don yellow ribbons in her honour until she is buried on Saturday.

“Fellow Kenyans, we are reminded that Mama Lucy loved bright colours. Therefore, the Kibaki family has identified the yellow ribbon as a symbol of the celebration of Mama Lucy,” Kenya’s Capital News quoted him as saying.

“Members of the public who wish to stand by the roadside as the convoy meanders through the road to pay their last respects are welcome to do so.”
