Two police officers were among four people who were killed when a vehicle they were escorting to Pangani Police Station in Nairobi was blown up on Wednesday night.

The officers had been manning a road block a few kilometres from the station when they intercepted the car and ordered the occupants to drive to Pangani Police Station for further investigations.
