Another bomb went off in Jos, the Plateau State capital, at about 9pm on Easter Sunday.
Though no one has been reported dead so far, the explosion comes hours after another one in Kaduna, Kaduna State, left over 20 persons dead on Sunday.
The explosion in Jos occurred in a park at Tudun Wada, with many said to have been injured.
Tudun Wada is close to the Plateau State Government House.
Other explosions in Jos earlier in the year had resulted in the death of Christian worshippers and the suicide bombers.
The first was at the headquarters of the Church of Christ in Nigeria, while the second was at St. Finbar’s Catholic Church.
