The incident happened when a
homemade bomb planted near a bus exploded as people were boarding at the Dukku
bus station, triggering a fire that consumed vehicles, authorities said.
"So far, 20 people have been
killed in the explosion and another 18 were badly injured," said Mato
Yakubu, Gombe state director of the National Orientation Agency (NOA).
An official with the Nigerian Red
Cross in the city said 20 bodies were evacuated to a local morgue.
