The dispute over the border stems from a rift between the Western-backed PA and Hamas Islamists who took control of Gaza more than a decade ago in a brief civil war.
Human rights groups say Rafah has been the sole exit point from Gaza for 95% of its population of 2million. Citing security concerns, Israel maintains tight restrictions on Palestinian movement at its border crossings.
PA employees were sent to Gaza’s border crossings with Israel and Egypt in 2017, a move that largely opened up Rafah for two-way traffic, after Egyptian mediation led to a Palestinian reconciliation deal, which has since faltered.
On Sunday, the PA announced its pull-out from Rafah, accusing Hamas of undermining its operations and detaining some of its workers. Since May, the crossing has been operating daily after sporadic openings for many years. On arriving in Gaza, Hani Abu Sharekh said he hoped Egypt would soon resume full operation of the facility to allow passengers out of the coastal enclave.
