President Mahmoud Abbas will canvas for support for the UN bid at a summit of 120 developing nations in Tehran, PA Foreign Minister Riyad al-Malki said Tuesday.

The PLO plans to ask the UN General Assembly to upgrade its status to a non-member observer state. A previous bid for full UN membership stalled at the Security Council last year.

Al-Malki told Ma'an he was confident Palestine had the support of the non-aligned states at the summit.

The Palestinian delegation will also discuss the issues of prisoners in Israeli jails and Israel's ongoing confiscation of Palestinian land, the PA minister said.

"Politically and diplomatically, we depend on the non-aligned movement and its support as its countries constitute the largest international gathering in the world," he added.

He said the Palestinian delegation would seek political and not financial support at the summit, as most states participating were developing countries facing their own economic difficulties.

It will ask states to boycott relations with Israel's Foreign Minister Avigdor Lieberman over his recent statements calling for Palestinian elections to replace Abbas, al-Malki said.
