Police in Kenya say seven people have been killed in tribal violence.

The Wednesday deaths came near the Tana River in eastern Kenya after more than 100 people launched an attack on a local village.

Coast Province police chief Aggrey Adoli said several houses were set on fire. The attackers are believed to be from the Pokomo community, while those killed are from the Orma community.

Adoli said there is deep rooted hatred between the communities caused by political competition. He said police are investigating politicians, businessmen and powerbrokers from the region for allegedly instigating the violence.

More than 100 people have been killed in a series of running clashes in the region.

Violence in the region could flare in early March when Kenya holds national elections.
