The United Nations has condemned the "inhumane acts of violence" in the Tana Delta and urged Kenyans to sue for peace ahead of the next General Election.

The UN Resident Humanitarian Coordinator in Nairobi Modibo Toure said the skirmishes in Tana River County needs to be contained and urged the government to act with speed to quell the loss of lives.

Mr Modibo said the UN and other international agencies “acknowledge the local peace and response efforts and the humanitarian assistance being provided to the affected communities” but said there was a need to determine the cause of the clashes.

“The United Nations would like to convey its condolences to the Government of Kenya, families and relatives of the communities affected by the current insecurity resulting from violent clashes in Tana River and other parts of the country,” he said in a statement Thursday.

"We would like to express our continued willingness to provide additional assistance in support of the Government and other humanitarian actors on the ground.”

Eleven people were killed on Wednesday morning following fresh fighting between Pokomo and Orma communities in the troubled Delta. Residents said suspected Pokomo raiders attacked Nduru Village in the morning killing six Ormas. The Ormas regrouped and killed five of the attackers.

On Thursday, another eleven people were killed in Kibusu village of Tana River County in what authorities said was a revenge attack.

The area has seen frequent violent attacks between the two communities since September last year. More than 200 people have been killed in the retaliatory violence in the past two months.

The Kenya Red Cross says at least 112, 000 people have been displaced since the violence began. The violence has continued unabated despite the government deploying nearly 2,000 police officers in the area.

On Thursday, the UN warned the violence could affect the next General Election if it is not tamed early.

“In the run up to the March 2013 elections, the United Nations would like to urge Kenyans to exercise their democratic rights in a peaceful manner with respect for the rights and dignity of all concerned.”
