Suspected Al Shabaab gunmen attacked a passenger bus on Tuesday, October 6.
According to Mandera South Deputy Commissioner Joshua Kitakwa, several people were injured in the attack which happened between Dabacity and Kutulo.
Unconfrimed reports stated that the Mecca bus was travelling from Nairobi to Mandera.
Authorities suspect that the terrorist group has been taking advantage of internal wrangles and infighting among residents to operate in the area.
The incident comes just weeks after three people were abducted in Mandera County.
Police told the media that the victims were masons travelling to Lafey Town for work.
The abduction happened about 30 kilometers from Lafey Town.
In August, over 50 suspected terrorists were reportedly seen crossing the Kenya-Somali border prompting Mandera County Commissioner Onesmus Kyatha to raise concerns during a security meeting.
"As we speak, I have received intelligence that about 50 members of the terror group have entered Kenya, and have ordered residents of Yedho area to vacate for them to take over," he explained.
The increased terrorist activity in the area has resulted in the resumption of construction of the controversial 700 km wall at the Kenya-Somalia border.
The perimeter wall is expected to have observation posts where electronic surveillance cameras to monitor movements on either side of the border.
