Assailants threw a crude homemade bomb into an Arabic school in southern Nigeria's Delta state overnight, police said, wounding seven people and escalating tensions between Muslims and Christians after a spate of church bombings across the nation.
Six of the wounded were children younger than nine.
The attack occurred at around 10pm and came two days after a series of Christmas Day bombings on churches and other targets by Islamist militant group Boko Haram claimed around 32 lives.
"Some men driving in a Camri car threw a low capacity explosive into a building where an Arabic class was taking place," police spokesman for the state Charles Muka said by telephone.
"Children aged between four and nine were taking a lesson. Six children were injured and one adult (was)," he added.
Northern Nigerian Christians said yesterday they feared that the Christmas Day bombings could lead to a religious war in the country.
The warning was made in a statement by the northern branch of the Christian Association of Nigeria, an umbrella organisation comprising various denominations including Catholics, Protestants and Pentecostalists.
