JOS – An explosion rocked the city of Jos on Saturday, Nigeria’s relief agency said, just days after at least 118 people were killed in a twin car bomb attack.

“There has been an explosion in Jos,” Manzo Ezekiel, spokesman for the National Emergency Management Agency (NEMA), told AFP but said it was not clear what caused the blast nor if there were casualties.

Pam Ayuba, spokesman for the Plateau state governor Jonah Jang, said the blast happened on Bauchi Road at about 9:30 pm (2030 GMT) and appeared to target football fans watching the European Champions League final.

On Tuesday, two car bombs suspected to have been planted by Boko Haram Islamists exploded within 20 minutes of each other in a crowded market in Jos, killing at least 118 people.
