Kenya's opposition is accusing security forces of killing more than 100 people, including children, in a crackdown on post-election unrest.
The party did not offer any proof of the claims on Saturday, and Reuters has only been able to confirm 11 deaths nationwide.
Speaking at a news conference, James Orengo, a top member of the NASA opposition coalition, said police had provoked the violence.
His colleague, Johnson Muthama, said NASA would not be cowed or relent under the pressure.
