“The Zionist regime’s officials should be tried for their crimes against Palestinians in Gaza,” he said.
“No one can confront Muslims and the resistance forces if the Zionist regime’s crimes against Palestinians continue … the bombardment of Gaza must stop immediately,” Khamenei added.
The remarks come ahead of US President Biden’s scheduled visit to Israel on Wednesday.
Israel-Hamas has entered its 11th day and in fresh developments from the war front, Hamas signaled an olive branch gesture by releasing a video of Israeli captives being treated as guests amid the deadliest air strike overnight that killed over 70 Palestinians.
Iran has warned that Israel-Hamas escalation could spread into a wider conflict and that TelAviv should stop the air strikes in Gaza.
The top U.S. general overseeing American forces in the Middle East made an unannounced trip to Israel on Tuesday amid escalated air strikes by Israel Air Force on the already devastating Gazan people who are facing the wreath of its neighbour country from land, sea, and air since the Hamas surprise attack.
He ensured Israel that the US military had what it needed as it fought a deepening war against the Palestinian group Hamas.
The trip by Army General Michael "Erik" Kurilla, head of U.S. Central Command, is the latest by a senior U.S. official to Israel ahead of an expected ground invasion by Israel's military in Gaza despite international condemnation and violation the international laws.
US President Joe Biden is also about to visit the Wednesday in Israel.
