Israel ceasefire talks in Qatar ended inconclusively, two Palestinian sources familiar with the matter said early on Monday, adding that the Israeli delegation didn't have a sufficient mandate to reach an agreement with Hamas.

The deal comes more than 20 months into the conflict -- and more than three months after a previous deal ended.

But it added: "In light of an assessment of the situation, Prime Minister Benjamin Netanyahu has directed that the invitation to proximity talks be accepted and that the contacts for the return of our hostages - on the basis of the Qatari proposal that Israel has agreed to - be continued. The negotiating team will leave tomorrow."
