Hamas said on Saturday that it would not disarm unless an independent Palestinian state is established in a fresh rebuke to Israel amid calls to end the war in Gaza.

Indirect negotiations between Hamas and Israel aimed at securing a 60-day ceasefire in Gaza and deal for the release of hostages ended last week in deadlock.

On Tuesday, Qatar and Egypt, who are mediating ceasefire efforts, endorsed a declaration by France and Saudi Arabia outlining steps toward a two-state solution to the Israeli-Palestinian conflict and saying that as part of this Hamas must hand over its arms to the Western-backed Palestinian Authority.

In its statement, Hamas - which has dominated Gaza since 2007 but has been militarily battered by Israel in the war - said it could not yield its right to 'armed resistance' unless an 'independent, fully sovereign Palestinian state with Jerusalem as its capital' is established.

Israel considers the disarmament of Hamas a key condition for any deal to end the conflict, but Hamas has repeatedly said it is not willing to lay down its weaponry.
