United Nations Secretary-General Antonio Guterres told President Donald Trump on Wednesday to avoid ethnic cleansing in Gaza after the U.S. leader proposed Palestinians resettle elsewhere and the United States take over the war-torn enclave.

Reiterating the UN's full commitment to the inalienable rights of the Palestinian people, Guterres called on the international community to work toward preserving the unity, contiguity, and integrity of the occupied Palestinian territory and the recovery and reconstruction of Gaza.

UN Secretary-General Antonio Guterres will warn against "ethnic cleansing" in Gaza over US President Donald Trump's suggestion, his spokesman has said.
