Hamas denounced on Monday a plan reportedly being considered by US President Donald Trump for the United States to take control of the devastated Gaza Strip and for its population to be relocated.

Almost two years since Israel began its campaign in Gaza, swathes of the Palestinian territory have been reduced to rubble and the vast majority of its population has been displaced at least once.

US media reported on Sunday that the White House is considering a plan that would see Gaza – home to roughly two million people – become a trusteeship administered by the United States for at least 10 years.

The goal would be to transform the territory into a tourism magnet and high-tech hub.

The outline also calls for at least the temporary relocation of all of Gaza's population, either through "voluntary" departures to other countries or into restricted, secured zones inside the territory.

Hamas political bureau member Bassem Naim slammed the proposal on Monday, asserting "Gaza is not for sale."

"Gaza is... part of the greater Palestinian homeland," he added.

Trump first floated the idea in February of turning Gaza into "the Riviera of the Middle East" after moving out its Palestinian residents and putting it under American control.

The idea drew swift condemnation from across the Arab world. (AFP)
