From AFP:

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.

Most recently, Jerf produced a documentary on the slaughter of Syrian activists in Raqa.
