Iran's supreme leader said it had been an "Islamic duty" to fight for the "liberation of Palestine" during a landmark speech Friday amid rising tensions with regional arch-enemy Israel.
Ayatollah Ali Khamenei lashed out at Western governments and their Arab "puppets" for supporting the Jewish state, in his first-ever address marking Quds (Jerusalem) Day.
The 80-year-old leader also seemed to confirm for the primary time that Iran has helped to supply Palestinians with arms.
The remarks came at the top of every week that saw Israeli Prime Minister Benjamin Netanyahu launch a Twitter tirade against Khamenei and reports that the 2 sides administered cyber attacks on one another .
"The aim of this struggle is that the liberation of the whole Palestinian land" and "the return of all Palestinians to their country," Khamenei said within the speech broadcast survive state television.
"The policy of normalising the presence of the Zionist regime within the region is one among the main policies of the us of America," he said.
"Some Arab governments within the region, which play the role folks puppets, have provided the required preconditions for this, like economic ties and therefore the like; these efforts are completely fruitless and sterile.
"Everyone must fill the hand of the Palestinian fighter and strengthen his back.
"We will proudly do our greatest during this way.
"One day we realised that the sole problem of the Palestinian fighter... was the shortage of weapons.
"We planned" to resolve this issue, and "the result's that the balance of power in Palestine has changed: today Gaza can get up to the Zionist enemy's military aggression and win."
Every year since the 1979 Islamic Revolution, Iran has marked Quds Day on the last Friday of Ramadan, the Muslim month of fasting, in solidarity with the Palestinians.
Khamenei was speaking at the event for the primary time in additional than 30 years as supreme leader, although he has repeatedly mentioned the Palestinian cause as "the main problem of the Muslim world".
Iran has cancelled its Quds Day rallies this year to curb the spread of the novel coronavirus, which first emerged within the country in February.
This year's commemoration comes after the assassination in January of Qasem Soleimani, the powerful commander of the Quds Force, the foreign operations arm of Iran's Revolutionary Guards.
Netanyahu on Wednesday blasted Khamenei on Twitter after the Iranian leader's own account posted quotes from a speech he made in November.
In the tweet on Khamenei's account, the Iranian leader was quoted as saying that "eliminating the Zionist regime doesn't suggest eliminating Jews".
Netanyahu responded by saying: "He should know that any regime that threatens Israel with extermination will find itself in similar danger".
The Iranian leader's tweets were also condemned by US Secretary of State Mike Pompeo and therefore the European Union .
The next day Israelis woke to a series of cyber attacks targeting websites of companies , municipalities and non-governmental organisations with a message in Hebrew and English: "the countdown to the destruction of Israel began long ago".
Earlier within the week, The Washington Post reported Israel had launched a cyber attack against the Iranian port of Shahid Rajaee, located on the Strait of Hormuz, an important route for international oil traffic.
This attack was thought to be in retaliation for a cyber attack against civil hydraulic installations in Israel.
In his speech, Khamenei also criticised the UN for failing to try to to its job in Middle East trouble spots.
"The main policy of arrogance and Zionism is to downplay the Palestinian issue within the minds of Muslim communities and to drive it into oblivion," he said.
Khamenei said the Syrian conflict, the Saudi-led war on Yemen's Iran-backed Huthi rebels and therefore the destruction of Iraq "are all tricks to entertain the resistance front and provides the Zionist regime the chance".
On the eve of his speech, the Arab League issued a press release condemning "Iranian interference within the internal affairs of Arab countries".
The Cairo-based organisation said such action "whether through direct intervention or through Iran's agents... constitutes a threat to regional stability".
