Excerps from an article at the BBC:
there are signs that a compromise could form around the plan for a buffer zone, which Turkey says is necessary to aid any refugee crisis and protect its own security interests.
"We want to keep all of the refugees there," Mr Gul said, stressing that Turkey was keen to avoid a repeat of the refugee crisis seen in Turkey in the first Gulf War in 1991.
Correspondents say Turkey would reserve the right to go beyond the buffer zone if it believed Iraqi Kurds were moving towards establishing an independent state.
