A top Hamas official warned on Wednesday that the ongoing Gaza border demonstrations — expected to reach their peak on May 15, known as “Nakba Day” by the Palestinians — would continue afterward, the Hebrew news outlet Maariv reported.

The protests, Ismail Haniyeh asserted in a speech, have drawn global attention back to the Palestinians and revived the issue of the so-called “right of return” of Arab refugees from the 1948 War.

Haniyeh, the head of the Hamas Political Bureau, threatened that the Trump administration would receive the “slap of the century,” instead of achieving its goal of achieving the “deal of the century” — an Israeli-Palestinian peace agreement.

He also predicted that the “Great March of Return” demonstrations would spread to Palestinian Authority-ruled areas of the West Bank.

A total of 38 Palestinian rioters have died in the unrest on the Israel-Gaza border that began on March 30.
