Police in the Kenyan port city of Mombasa say they have arrested two people who were driving a car with two improvised bombs hidden inside it.
The suspects, one Kenyan and the other of Somali origin, were planning to attack an unspecified target, they say.
The arrests followed a tip off, a police official added.
Kenya is on a heightened state of alert after militants from Somalia’s al-Shabab Islamist group attacked a shopping centre in Nairobi last year.
Security was increased further following Monday’s incident.
« We have not established where the target was, but we have detained two terror suspects who were in the vehicle, » said Henry Ondiek of the Mombasa Criminal Investigation Department.
« We were tipped off that the two were headed for an attack on an unspecified place and we laid an ambush, » he said.
Two homemade bombs were found in the car along with a mobile phone, which could have been used as a detonator, according to police.
In last September’s attack, at least 67 people died when al-Shabab stormed the Westgate shopping centre.
In February more than 100 people appeared in court in Mombasa accused of being members of al-Shabab, after a raid on a mosque.
Al-Qaeda-affiliated al-Shabab has carried out a series of attacks in Kenya in what it says is retaliation for Nairobi’s decision to deploy troops to Somalia.
