Nairobi - Gunmen killed five Kenyan policemen and wounded at least two others on Tuesday in an ambush in the troubled north-east border region close to war-torn Somalia, police said.
Insurgents sprayed a police patrol with gunfire near the border town of Liboi, leaving some officers badly wounded, in the latest in a string of attacks in the restive region.
“Five were killed on the spot when they were ambushed out on patrol, and we are told many bullets were fired on their vehicle,” said a senior police officer who asked not to be named. “Others have been critically injured.”
The identity of the perpetrators remains unclear, but such attacks against police and other targets are frequent along Kenya's porous border with Somalia and are routinely blamed by the authorities on the al-Qaeda-linked Shebab.
The region along Kenya's 700-kilometre border with Somalia has seen a series of attacks, mainly on police but also against hotels and restaurants.
Liboi, about 550 kilometres north-east from the capital Nairobi, hosts a military base and is used by the army as a staging point to supply troops fighting the Shebab as part of an African Union force inside southern Somalia.
“There is a heavy security presence now, more officers have been sent to get them before they cross the border,” the officer added.
The attack comes as Kenya gears up to celebrate 50 years of independence on Thursday from former colonial masters Britain.
Kenya has said border security has been stepped up since the Shebab claimed responsibility for Nairobi's Westgate mall massacre in September in which at least 67 people were killed.
The Shebab have been driven out of fixed positions from major towns in Somalia by the UN-mandated AU force, but still regularly launch attacks that include bombs and guerrilla-style raids.
