Nigerian authorities detained an opposition leader last Thursday ahead of a mass anti-government protest. "They think that by arresting and detaining him they will stop the mass action, but they will not be able to," Balarabe Musa, chairman of the opposition-dominated Conference of Nigerian Political Parties, told Reuters. The group's mobilisation committee chairman Buba Galadima was detained by intelligence officers of the State Security Services in the capital Abuja, he said.
