RBSS is a group of citizen journalists who work to expose human rights abuses in Raqa, the northeastern city that IS uses as its de facto capital in Syria.
A friend of Jerf’s said he had been “supposed to arrive in Paris this week after receiving, along with his family, a visa for asylum in France”.
Jerf was also editor in chief of Hentah, a Syrian magazine that reports on the “daily lives of Syrian citizens”, said the publication’s website.
In a statement, the Committee to Protect Journalists said that Jerf was shot outside a building in Gaziantep that houses Syrian opposition media. ISIS has not taken responsibility for the killing, but CPJ reports that some of its supporters celebrated Jerf’s death on Twitter.
