The first session of indirect Hamas-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.

Talks over a potential ceasefire in Gaza are set to resume in Doha, Qatar, though major differences between both sides’ positions remain an obstacle.

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