Hamas is open to a years-long truce with Israel in Gaza but is not willing to lay down its arms, an official said, as leaders of the Palestinian fighter group met mediators in Cairo for ceasefire talks, AFP reports.

Sources close to the talks told Reuters Hamas hoped to build support among mediators for its offer, adding the group might agree to a five to seven-year truce in return for ending the bombardment, allowing for the rebuilding of Gaza, the freeing of Palestinians jailed by Israel and the release of all hostages.

“The idea of a truce or its duration is not rejected by us, and we are ready to discuss it within the framework of negotiations. We are open to any serious proposals to end the war,” said Taher Al-Nono, the media adviser for the Hamas leadership, in the first clear signal that the group was open to a longer-term truce.

However, Nono ruled out a core Israeli demand that Hamas lay down its arms. Israel wants to see Gaza demilitarised.

“The weapon of resistance is not negotiable and will remain in our hands as long as the occupation exists,” Nono said.
