Six people were wounded Wednesday when an explosive device went off at the Dadaab refugee camp in northeastern Kenya, the Kenyan Red Cross said.
The device, believed to be a hidden bomb, exploded as non-food items from an aid agency were handed out in Dadaab, the world's largest refugee camp, which houses over 465,000 refugees, mainly Somalis fleeing drought and conflict.
The Red Cross said the explosion wounded six people while an AFP reporter said the injured included three policemen.
Regional police chief Phillip Tuimur confirmed the blast, the latest in a string of attacks in the region. Dadaab lies some 100 kilometres (60 miles) from the border with war-torn Somalia.
No one has claimed responsibility, but Kenya has in the past blamed similar explosions on Somalia's Al-Qaeda linked Shebab or their supporters.
Kenyan troops invaded Somalia in October, and the hardline Shebab have vowed revenge ever since.
