This comes in the wake of the arrest of six suspected Al-Shabaab militants on Tuesday in Ruka area along the Kenya-Somalia border.

Three grenades, two pistols and 84 rounds of ammunition were also seized from their vehicle.

Garissa County Commissioner Mohamed Maalim said they have been on high alert after security officers received intelligence of a possible terror attack, local media reported.

“The information we have received is that some suspected terrorists are planning to carry out attacks during this Christmas season,” Mr Maalim said.

He said police officers from the rural border patrol unit came across a Toyota Land Cruiser vehicle with 10 occupants, which sped off after being waved down to stop.

“Our team of officers gave chase and caught up with them. Four of them jumped out of the vehicle and escaped on foot,” Mr Maalim said.

Kenya has been hit by a series of grenade attacks in which more than 50 people have been killed and scores injured. Al-Shabaab has, in the past, claimed responsibility for some of the attacks, saying, it was in retaliation to Kenya’s decision to send its troops to the war-torn Horn of Africa country.
