Nigerian authorities should investigate attacks by security forces on journalists at a recent protest in Abuja, and hold those responsible to account, the Committee to Protect Journalists (CPJ) said on Saturday.

247NewsAfrica reports that on November 12, security forces fired live rounds to disperse a group of demonstrators at the department of state services (DSS) headquarters in Abuja, the capital, and shot at journalists and beat at least one reporter, according to journalists who spoke to CPJ, news reports, and a video of the protest uploaded to YouTube by the International Centre for Investigative Reporting, the CPJ said in a statement.

Demonstrators gathered at the DSS building to call for the release of Omoyele Sowore, a political activist and founder of the Sarah Reporters news website, according to those reports. No one was shot in the incident, according to the journalists who spoke to the CPJ.

“There is absolutely no justification for security officers to shoot at or attack journalists working to cover a protest,” said Angela Quintal, CPJ Africa program coordinator, in Washington DC.

“Nigerian authorities must investigate allegations that department of state services agents targeted journalists doing their job and hold those responsible to account,” she said.
