A citizen journalist group that reports secretly from the Islamic State stronghold of Raqqa is being honored with a $50,000 prize for courage.

The New York-based Train Foundation announced Thursday that this year's Civil Courage Prize will go to the group Raqqa is Being Slaughtered Silently .

The group was formed in 2014 after Islamic State militants took over the Syrian city of Raqqa and declared it to be their capital.

The citizen journalists work anonymously to publicize lashings, beheadings and other abuses by the Islamic State group, also known as ISIS or ISIL.

Raqqa is Being Slaughtered Silently says its members have been abducted, tortured and killed in retaliation for their work.

The Civil Courage Prize was founded in 2000 and recognizes "resistance to evil at great personal risk."
