Six people have been arrested in Nigeria in connection with deadly unrest following a series of bombings that killed over 30 people in central Nigeria, officials say.
No arrests have yet been made in connection with the Christmas Eve explosions, but those arrested are suspected to have participated in street violence Sunday that left at least three dead and dozens wounded, Plateau state police chief, Abdurrahman Akano, said on Monday.
Clashes erupted after a total of seven explosions hit the densely populated areas in the city of Jos on Christmas Eve.
The city was the scene of violent clashes on March 7, when members of the local Muslim and Christian communities fought each other in revenge for previous killings. Police said 109 people were slain in the clashes, mostly women and children.
During Sunday clashes, angry youths barricaded roads and attacked people passing by, setting several houses on fire. A truck and several cars were also set ablaze.
Military patrolled the streets of Jos on Monday and security officials cordoned off the areas where the violence had erupted.
The United Nations Secretary General Ban Ki-moon has condemned the violence "especially at a time when millions of Nigerians were celebrating religious holidays," UN spokesman's office said.
Nigerian President Goodluck Jonathan has expressed his sympathy to the victims' families and said the government will bring the perpetrators to justice.
