The Gaza leader of the Hamas militant group says protests along the Israeli border next week will be "decisive."

Speaking to hundreds of youths, Yehiyeh Sinwar said Wednesday that weeks of mass protests will climax on May 14, when the U.S. moves its Israel embassy to Jerusalem and Palestinians mark 70 years of displacement from homes in what is now Israel.

He said the protests will be "like a tiger running in all directions."

Sinwar told the crowd that Hamas leaders are "ready to die along with tens of thousands" to break an Israeli-Egyptian blockade and realize a dream of returning to lost properties in Israel.

Some youths brandished wire cutters, often used by protesters trying to break through the border fence.

Israeli fire has killed 40 during weekly protests.
