A group that has been key in organising protests against police brutality that have gripped Nigeria in the last two weeks has urged people to stay at home. The Feminist Coalition also advised people to follow any curfews that may be in place in their states. President Muhammadu Buhari called for an end to the protests in a TV speech. The streets of Nigeria's biggest city, Lagos, the centre of the protests, remained quiet on Thursday night but there is an atmosphere of fear. Lagos and other parts of Nigeria have seen buildings torched, shopping centres looted and prisons attacked since Tuesday night's shooting of protesters in Lagos. Rights group Amnesty International said security forces killed at least 12 people, although Nigeria's army has denied its involvement. The protests began on 7 October with mostly young people demanding the scrapping of a notorious police unit, the Special Anti-Robbery Squad (Sars). Although President Buhari said it had been dissolved on 11 October, the protests have carried on, and broadened to include demands for broader reforms in the way Nigeria is governed.
