Palestine on Wednesday called for the "immediate, full lifting of the Israeli blockade" and "the sustained opening of Gaza's border crossings for the movement of persons and goods", Xinhua reported.
The statement came as Palestinian Permanent Observer to the United Nations Riyad Mansour was taking the floor at an open debate of the UN Security Council on the situation in the Middle East.
"It is vital for allowing the long-overdue reconstruction process to truly get underway and to allow for economic and social recovery through the restoration of livelihoods, dignity and hope, " Mansour said.
He said he "deplored" the escalation of violence, particularly the recent Israeli military attacks in Gaza and the perpetration of "yet another" extrajudicial killing of a Palestinian in the recent period, raising tensions and instability.
Israel did not renew a 10-month settlement moratorium when it expired at the end of September and Palestinian President Mahmoud Abbas has refused to resume peace talks with Israel until it ends all settlement activity.
Mansour said he thought it was "unimaginable" that two years have passed since the December 2008-January 2009 Israeli military aggression in the Gaza Strip and the Palestinian people are still being prevented from reconstructing and rehabilitating their communities and lives.
The "cumulative impact" of the "illegal" Israeli policy on the continuity, integrity, unity and viability of the Palestinian Territory has been "destructive, with an equally destructive impact on the drive for peace," he said.
He said Palestine currently faces "an impasse" and "the further erosion of trust and confidence between the parties."
Mansour said he is grateful for the "principled position" taken now by 107 member states to extend recognition to the State of Palestine on the basis of the pre-1967 borders, in line with the relevant UN resolutions and the international unanimity on the two- State solution for peace.
He said he was "heartened" by the political, humanitarian and developmental support and solidarity extended to Palestine from all corners of the globe.
"Despite our deep disappointment and frustration in the recent period, we have not lost hope and will continue to strive to achieve our legitimate national aspirations, refusing to allow the occupying Power to unilaterally determine our fate and destiny as a people," Mansour said.
