Villagers die in Kenya clan raid
At least 22 people have died in an attack on a village in north-eastern Kenya in a revenge killing between rival Somali clans.
The BBC's Bashkash Jugsodaay said eight militiamen were also killed after a clash with police.
Since December some 50 people, mainly women and children, have died in violence in Mandera district.
The area's severe drought is causing the Garre and Murule clans to battle for control of water and pastures.
Land degraded
Police believe Murule militiamen killed the Garre villagers and Mandera's provincial commissioner said a security operation has been launched.
Nobel Peace Prize winner Wangari Maathai, Kenya's deputy environment minister, said in January she was ready to use her influence to reconcile the warring clans.
But our correspondent says there has been little evidence so far of efforts by authorities to resolve the dispute.
The communities grazing their livestock are scattered over a large area and police find it difficult to monitor, he says.
Professor Maathai said frequent clashes in Kenya and Somalia were rooted in land degradation and conflicts between pastoralists and farmers.
