No fewer than 20 persons were reported dead on Monday when two female suicide bombers struck in Maiduguri, the Borno State capital.
The attack was said to have been carried out at about 4pm.
Details were still sketchy as at press time.
Maiduguri had been attacked by the dreaded Boko Haram sect no fewer than three times in the last three weeks.
This comes in the wake of the determination of President Muhammadu Buhari to put an end to insurgency in the country.
