Kenyan police have been involved in a fierce gun battle with militant Islamists in north-eastern Garissa County, leaving one officer wounded, a government spokesman has told the BBC.

The al-Shabab militants had ambushed the police near Yumbis village in Garissa County, Mwenda Njoka added.

He dismissed as propaganda al-Shabab’s claim that at least 20 policemen were killed in the attack.

Al-Shabab is a Somalia-based group which has stepped up attacks in Kenya.

In April, it carried out a siege on Garissa University College and 148 people were killed.

Last week, the militants briefly invaded a mosque in Yumbis and warned residents not to work with the government.

BBC Africa security correspondent Tomi Oladipo says al-Shabab appears to be entrenching itself in Kenya, despite government efforts to defeat the militants.
