NAIROBI (AFP) - A grenade attack wounded four people in Kenya's Wajir border region with war-torn Somalia, police said Thursday, the latest in string of attacks in the volatile region.
Attackers in Wajir, some 100 kilometres (60 miles) from Somalia, hurled grenades into a restaurant and a shop late on Wednesday, said regional police chief Philip Tuimur.
"We are looking for the attackers, none of them has been arrested," he said. "Some of the people injured have been discharged from hospital."
Kenya has suffered a spate of grenade attacks, shootings and bomb blasts since sending troops into southern Somalia in October to crush Shebab bases there, prompting warnings of revenge attacks by the Islamist fighters.
Last month attackers in the border garrison town of Garissa carried out Kenya's worst attack in a decade, when they targeted worshippers as they held Sunday prayer services, killing 18.
