Sounds from some streets in parts of Nigeria on Saturday as millions poured onto the streets to protest against bad governance and insecurity, as well as the recent Twitter ban by the government of President Muhammadu Buhari.

Activists had called for the nationwide protests on Democracy Day, which marks Nigeria’s move to civilian rule more than 20 years ago.

The protests however took a violent turn when police fired tear gas to disperse the anti-government protesters in Lagos and the capital, Abuja, with reports of arrests and injuries.

There were also pockets of protests in Ibadan, Osogbo, Abeokuta and Akure, all in southwestern Nigeria.

Here are some of the protesters.
