RNA - "The Yemeni people will always be against the United States and Israel. and will remain pro-Palestine and support its cause," Abdul-Malik Badreddin al-Houthi was quoted by Yemen's al-Masirah network.
"I call on the dear Yemeni people to participate tomorrow in Quds Day," he added, referring to the last Friday of the holy Muslim month of Ramadan.
This year's Quds Day rallies come weeks before a high-profile summit in the Bahraini capital Manama, where the administration of US President Donald Trump is expected to unveil its so-called "deal of the century" to end the Israeli-Palestinian conflict.
The deal, which has been branded as dead on arrival by analysts due to overwhelming opposition from Palestinian groups, reportedly seeks to swap Palestinians' right to statehood with limited autonomy and basic economic incentives.
Houthi warned Thursday that elements within the Islamic world were promoting the deal.
"Trump's deal depend on roles played by some inside the Islamic ummah," he said, referring to reports that some Arab regimes have been pressuring Palestinian authorities to accept the deal.
The Ansarullah leader warned that resistance was the only way forward if Palestinians really sought victory against the US and Israel.
"The resistance proved fruitful and accomplished some victories against the Zionist enemy," he asserted.
He described the US and Israel as "a common threat to the Islamic world" and noted that America's role in tensions across the region had become more obvious over the recent weeks.
The International Quds Day is a legacy of the late founder of the Islamic Republic, Imam Khomeini, who designated the day in solidarity with Palestinians.
Since the 1979 Islamic Revolution in Iran, the International Quds Day has been held worldwide on the last Friday of the Muslim fasting month of Ramadan.
