Government officials in Rakhine State originally blamed the RSO, an Islamist insurgent group mainly active in the 1980s and 1990s, for the attacks;[95] however, on 17 October 2016, a group calling itself Harakah al-Yaqin (later changed to the Arakan Rohingya Salvation Army or ARSA) claimed responsibility.[96] In the following days, six other groups released statements, all citing the same leader.[97]
