UN agency chief says Israel trying to force Gazans into Egypt

The head of the United Nations agency for Palestinian refugees has accused Israel of laying the groundwork for the mass expulsion of Gazans across the territory's border into Egypt.

More than two months of Israel's war on Gaza has displaced most of Gaza's population, but Palestinians are largely barred from leaving the narrow besieged territory.

In an opinion piece published on Saturday in the Los Angeles Times, UNRWA chief Philippe Lazzarini pointed to the worsening humanitarian crisis in Gaza and the increasing concentration near the border of displaced civilians who fled the fighting, first in the north and then further south.

"The United Nations and several member states, including the US, have firmly rejected forcibly displacing Gazans out of the Gaza Strip," Lazzarini said.

"But the developments we are witnessing point to attempts to move Palestinians into Egypt, regardless of whether they stay there o rare resettled elsewhere."

The widespread destruction in the Palestinian territory's north and the resulting displacements were "the first stage of such a scenario", he added, while forcing civilians from the southern city of Khan Younis closer to the border was the next.

"If this path continues, leading to what many are already calling a second Nakba, Gaza will not be a land for Palestinians anymore," Lazzarini said, using the Arabic term for the exodus or forced displacement of 760,000 Palestinians during the war that coincided with Israel's creation in 1948.

A spokesperson for the Israeli defence ministry office responsible for Palestinian civilian affairs did not immediately respond to a request for comment on Lazzarini's accusation.

When asked about the possibility of evacuating people into Egypt last week, a government spokesman said Israel was "focusing on getting civilians out of harm's way inside the Gaza Strip".

A small number of Gazans have been allowed to cross into Egypt for medical treatment, and some foreign nationals trapped in the territory at the outset of the war were also allowed to evacuate by way of the Rafah crossing -- Gaza's only border not under Israeli control.

But other Palestinians are currently blocked from leaving, with the territory's estimated 1.9 million displaced people, out of a population of 2.4 million, turning the border town of Rafah into a vast camp.

Israel's war on the Gaza Strip  has killed at least 17,700 people, according to Gaza's Hamas-run health ministry.

Aid groups have sounded the alarm on the "apocalyptic" humanitarian situation in the narrow territory, warning it is close to being overwhelmed by disease and starvation.
