The decision was made at a meeting in Doha attended by Palestinian leader Mahmoud Abbas.

Mr Abbas had reiterated his determination to seek UN recognition in September unless Israel began negotiations on a "substantial basis".

US-led peace talks between Israel and the Palestinians have been stalled for months.

A statement issued by the Arab League monitoring committee on Saturday said it "supports the appeal to the UN asking that Palestine, within the 1967 borders, becomes a full-fledged state" of the international organisation.

On Friday, UN General Assembly president Joseph Deiss said that a Palestinian state would need the support of all five veto-wielding permanent members of the Security Council to be recognised.
