Four primary school children have been killed during an attack on a police camp in north eastern Kenya on Tuesday.
The militants also destroyed a phone mast.
The boarding school is on the road between Garissa and Dadaab and more than 100 children stay in the boarding house.
Residents say that when the children heard the gun shots they scattered and it is believed some got caught by stray bullets.
An eye witness said they had seen militants in the area a week ago and had reported it to the authorities but nothing was done.
No one has claimed the attack but an eye witness said residents saw fighters from the militant Islamist group al-Shabab in the area a week ago and reported it to the authorities.
Al-Shabab are known to attack communication masts so that people cannot contact the rest of the country.
