Turkey's President Recep Tayyip Erdogan said that the chance for peace in Gaza after the humanitarian pause was lost for now due to Israel's uncompromising approach, broadcaster NTV reported on Saturday.

"We have always emphasized that we are in favor of a permanent cease-fire rather than a humanitarian break … There was an opportunity for peace here, and unfortunately, we have lost this opportunity for now due to Israel's uncompromising approach," Erdogan was quoted as saying by NTV and other Turkish media.

The truce that started on Nov. 24 had been extended twice. But after seven days during which women, children and foreign hostages were freed as well as a number of Palestinian prisoners, mediators failed to find a formula to release more.

Since then Israeli airstrikes and artillery bombardments have hit southern Gaza, extending the nearly two-month-old war in which thousands of people died.

Speaking to reporters on his way back from the United Arab Emirates, Erdogan also said that he is not losing hope for a lasting peace in the conflict adding that Hamas cannot be excluded from its potential solution, according to NTV.

"We need to focus on the two-state solution … The exclusion of Hamas or destruction of Hamas is not a realistic scenario," Erdogan said during the interview, adding that he will not define Hamas as a terrorist organisation.

Separately, sources told Reuters that Israel has informed several Arab states that it wants to carve out a buffer zone on the Palestinian side of Gaza's border to prevent future attacks as part of proposals for the enclave after war ends.

Erdogan also said a contact group formed by the OIC and Arab League would visit the United States to discuss possible resolution of conflict in Gaza after meeting with authorities in London, Paris, Barcelona and the United Nations.
