evidence: According to the report, which was based on interviews with 23 Rohingya eyewitnesses and "open-source video and photographic evidence" of the massacre, a crowd estimated in the thousands of Rohingya civilians gathered on the banks of the Naf River on the morning of August 5. The group had fled an AA offensive on Maungdaw and were seemingly "waiting for boats to cross over into Bangladesh." [...] Fortify Rights also offers a likely explanation for why the AA might have chosen to target the crowd gathered on the banks of the Naf River. It cites Rohingya eyewitnesses as stating that they saw armed fighters from the Rohingya Salvation Organization (RSO), a Rohingya militant group allied with the military junta, among the crowd. These fighters were also reportedly seeking to escape to Bangladesh at the time of the attack.
