At least one person was killed and three others injured after suspected al Shabaab militants attacked vehicles near Nyongoro area on Lamu-Garsen road, Lamu, on Tuesday morning.
Police said Hindi MCA James Kariuki Njagaa was among the victims of the attack.
He survived alongside his wife.
Security forces from the Special Operations Group and the forest rangers responded to the incident and rescued the injured victims, who were taken to Witu Level 4 Hospital for treatment.
As a result of the attack, several vehicles and buses heading to Mombasa were stopped at Witu area.
Lamu West deputy county commissioner Gabriel Kioni confirmed the incident and added the injured were taken to hospital after the Tuesday morning incident.
Witnesses said the terrorists attacked three civilian vehicles in Lamu on Tuesday morning August 1.
The gang targeted the vehicles using the Lamu-Witu route using Rocket Propelled Grenades and assault rifles, police and witnesses said.
A security team that responded to the scene was attacked by an RPG to delay their response.
This delayed the response in general amid fears of more deaths.
More security was sent to the ground to pursue the attackers.
This comes days after the same gang killed a police reservist and injured two others in Biyamathowa borehole 20 kilometres outside the Dadaab refugee camp in Garissa.
The incident happened on July 28, officials said adding more personnel had been sent to pursue the attackers.
