Two British journalists with Vice News were released from Turkish custody on Thursday, however Iraqi journalist Mohammed Ismael Rasool remains in custody.
Jake Hanrahan and cameraman Philip Pendlebury were arrested in the Kurdish region near Diyarbakir last week and charged with "working on behalf of a terrorist organisation".
Their lawyer, Ahmet Ay, told the BBC a Turkish court had accepted an appeal of release for Mr Hanrahan and Mr Pendlebury, however, the court rejected an appeal for Mr Rasool's release, saying material on his computer was still being investigated.
"We are planning to appeal to this decision as well, most probably next week. We think all the three journalists' actions were within the frame of journalism," he said.
