At least seven people were killed in shoot-outs and other attacks after a tribunal annulled the election of the governor of Nigeria's eastern Taraba state and replaced him with a ruling party candidate, police said.
Attackers shot sporadically and set fire to buildings on Sunday, a day after the announcement of the order that Darius Ishaku, a Christian from the opposition Peoples' Democratic Party, had not legally won an April vote, police added.
