More than 20 people have died after a fuel tanker slammed into the back of a line of cars waiting at a police checkpoint in central Nigeria.
The crash happened as vehicles waited on the border of Plateau and Bauchi states in Nigeria's fertile "middle belt" region on Friday.
At least 20 vehicles caught fire in the ensuing explosion and blaze that spread across the two-lane highway running through the town of Narabi.
The roadblock was in place as Nigeria faces heightened security with the start of its three-week election period.
Fatal traffic crashes are common in Nigeria, where old roads are rarely maintained and drivers often ignore speed limits and safety regulations.
