Kenyan police say gunmen opened fire on Chinese construction facilities in an eastern area, days after extremists claimed responsibility for a deadly attack in Nairobi.
National police chief Joseph Boinnet says security forces fought off the attackers at Shimbirey near Garissa town on Sunday.
There are no reports of casualties.
Al-Shabab, an extremist group linked to al-Qaeda and based in Somalia, claimed responsibility for a 2015 attack in Garissa that killed 147 people, mostly students.
Al-Shabab also says it carried out the Jan. 15 attack at a hotel and office complex in Nairobi that killed 21 people, including a police officer. All five assailants also died.
