Nigeria's military has killed hundreds of Shiite Muslims, activists said, in what the country's top human rights protector is calling "a massacre".
Chidi Odinkalu of the Nigerian Human Rights Commission posted photos on social media showing a bulldozer tearing apart a shrine of the Islamic Movement in Nigeria, adding that detained leader Ibraheem Zakzaky's home also was destroyed.
Mr Odinkalu said Mr Zakzaky suffered four bullet wounds and one of his wives was killed in raids that began on Saturday and ended on Monday morning.
He tweeted: "Citizens must ask who ordered this carnage?"
Nigerian troops said the raids came after 500 Shiites blocked the convoy of Nigeria's army chief and tried to kill him.
