Nairobi (Alshahid)-Two mass graves have been discovered in Kenya’s coastal Tana Delta region.

Kenya Deputy Police Spokesman Charles Owino confirmed on Tuesday the reports adding that police are seeking court order to exhume the bodies in Ozi Village and carryout further investigation.

“We have information of mass graves where attackers buried their own in retaliatory attacks and the village is believed to be where attacks were planned,” Owino said.

According to police the graves were dug 40 meters from Tana River.

The conflict in the Tana Delta region pits the Orma people, a semi-nomadic tribe of cattle herders, against the Pokomo people, who rely more heavily on agriculture. Though their rivalry has deep roots, this recent violence may be predicated on politics.

About 118 deaths were recorded, including those of nine policemen, on August 22 when the crisis started at the village of Riketa in Tana River County. The attack led to revenge attacks on September 7, 10, and 11.

Human rights groups have been calling on the government to probe the killings, insisting that investigations should extend to organizers and politicians linked to the Tana Delta clashes in which more than 6,000 were displaced.
