“Those of the Ifo attack were all casual labourers working at a primary school doing construction,” said Leo Nyongesa, North Eastern PPO.
Nyongesa said that a second blast at a hotel in Wajir, popular with government officials, had wounded at least one person.
The hotel in Wajir is on a road leading to a military camp, and is close to a government club that was also attacked in 2011.
Grenade and improvised explosive device (IED) attacks in Kenya have become more frequent since troops were sent troops to Somalia to pursue al Shabaab insurgents it blames for a wave of kidnappings in 2011.
