Protesters have marched through the streets of Nigeria’s capital, Abuja, to the Saudi embassy carrying placards condemning the killing of Saudi journalist Jamal Khashoggi.

He was murdered in the Saudi consulate in the Turkish city of Istanbul three weeks ago, investigators say.

The small group of demonstrators, wearing black T-shirts, were mainly journalists and human rights activists, including staff from Amnesty International in Nigeria.

They called on the UN to launch an independent investigation into the murder and ensure the perpetrators are brought to justice.
