Eight Dutch members of ISIS have been executed after they allegedly attempted to desert from the terror group, a Syrian activist said Monday. 

Abu Mohammad, a member of the citizen journalist group Raqqa Is Being Slaughtered Silently (RBSS), said on Twitter that the killings had taken place Friday in Maadan, Raqqa Province, not far from the capital of the self-proclaimed caliphate.

RBSS said that the attempted desertions stemmed from a dispute between approximately 75 Dutch militants and some of the terror group's Iraqi intelligence operatives. It claimed that ISIS leaders in Raqqa had sent an intermediary to resolve the conflict, but the intermediary was killed. 

In response, ISIS leaders in Iraq reportedly ordered the arrest of all the members of the Dutch cell. 

RBSS also said that three other Dutch jihadists had arrested by Iraqi ISIS members who accused them of attempting to flee, and one of those men had been beaten to death during an interrogation. 

The Dutch security services estimate that approximately 200 people from the Netherlands, including 50 women, have joined ISIS. Some of them are believed to have previously immigrated to Holland from Morocco.
