TEHRAN: Iran´s president on Monday insisted "enemy" plots against the country would fail as vast crowds marked 40 years since the Islamic revolution at a time of heightened tensions with the United States.
Tensions between Washington and Tehran are high after the USA withdrew from an worldwide nuclear deal aimed at curbing Iran's nuclear ambitions, and re-imposed sanctions that have hurt the Iranian economy.
In his address on Tehran's Azadi Square, Rohani said the "enemy will never reach its evil objectives", vowing that Iran will defeat USA sanctions.
The large turnout at these state-sponsored rallies comes as Iranians faces rising prices and food shortages which have triggered waves of protests.
Hundreds of thousands of Iranians marched and some burned USA flags on Monday to mark the 40th anniversary of the triumph of Ayatollah Ruhollah Khomeini, the Shi'ite cleric who toppled the Shah in an Islamic Revolution that rattles the West to this day.
Iran displayed its ballistic missile capabilities during Tehran rally, parading two missiles capable of reaching up to 800 kilometres.
Despite Iran's efforts to hide the facility, Israel has nevertheless discovered, tracked and uncovered it, the network said, as part of its effort to thwart Iran's military entrenchment in Syria.
U.S. President Donald Trump pulled out of Iran's 2015 nuclear deal with world powers previous year and re-imposed sanctions on Tehran, dealing a blow to the country's economy.
"The presence of people today on the streets all over Islamic Iran means that the enemy will never reach its evil objectives", Rouhani himself told the crowds, vowing the "US conspiracy" against Iran will never succeed. But he remained defiant as Iranians recalled the end of a monarch who catered to the rich and unleashed secret police on dissenters.
"The Iranian people have and will have some economic difficulties (due to the sanctions) but we will overcome the problems by helping each other", Rouhani said.
But if the U.S. does attack, he warned, "We will raze Tel Aviv and Haifa to the ground".
The Israeli prime minister's comments came in direct response to IRGC political affairs spokesman Yadollah Javani, who warned earlier on Monday that Iran would attack Israel if threatened by Washington.
Hundreds of thousands of Iranians celebrated the anniversary all over the country. "They should take this into account".
The United States and its Arab allies have viewed Iran with great suspicion since the Islamic Revolution swept the Shah from power in 1979, fearing Khomeini's radical ideology would inspire Islamic militants across the Middle East.
Today, Iran enjoys growing influence through proxies in Iraq, Syria, Lebanon and Yemen, raising concerns in Sunni Saudi Arabia, which accuses its rival of trying to dominate the Middle East. Tehran denies that.
