Gaza and the West Bank should eventually be “reunited” under a new Palestinian Authority, US President Joe Biden said in an opinion piece.

“As we strive for peace, Gaza and the West Bank should be reunited under a single governance structure, ultimately under a revitalized Palestinian Authority, as we all work toward a two-state solution,” Biden wrote in the piece published in The Washington Post.

“A two-state solution is the only way to ensure the long-term security of both the Israeli and Palestinian people. Though right now it may seem like that future has never been further away, this crisis has made it more imperative than ever,” Biden said.

He also threatened sanctions against settlers committing violence against Palestinians in the West Bank amid the conflict in Gaza.

“I have been emphatic with Israel’s leaders that extremist violence against Palestinians in the West Bank must stop and that those committing the violence must be held accountable,” he said.

“The United States is prepared to take our own steps, including issuing visa bans against extremists attacking civilians in the West Bank.”
