At least one person injured in a blast targeting a voter registration centre at Ifo refugee camp near Kenya-Somalia border.

Police say the blast was caused by an Improvised Explosive Devise (IED) planted in one of the Independent Electoral and Boundaries Commission voter registration centres at the refugee camp.

The IED is suspected to have been planted by Al Shabaab sympathizers and targeted voter registration clerks.

It is not yet clear whether the person injured works for IEBC.

Kenya has experienced a string of gun and grenade attacks since it sent troops into Somalia to pursue Al Shabaab rebels.

Recently, officials said a message intercepted from Al Shabaab shows the terror group was offering up to Sh890,000 to kill Kenyan security officers.

Garissa County Commissioner Maalim Mohammed said the rewards are enough incentive to motivate some youths in the North Eastern to carry out attacks against Kenyan army and police.

The pay by Al Shabaab varies with the security officer's rank.
