Iran on Saturday marked Army Day with a military parade featuring new weapons systems, as well as a truck carrying a massive banner reading “Death to Israel.”

A televised broadcast of the parade was punctuated by repeated cries of “Death to America” and “Death to Israel.”

“If Israel makes a mistake,” the announcer on Iran television said during the broadcast, as heavy trucks carrying armored personnel carriers rolled past, “those in Tel Aviv and Haifa will not sleep at night, not one person.”

Broadcast on national television, military brass and political leaders, foremost President Hassan Rouhani, attended the procession south of the capital Tehran, which showcased the country’s military technologies.

Among the weapons systems paraded past dignitaries was a domestically produced version of the Russian S-300 anti-aircraft missile, the Bavar 373.

Speaking at the event, Rouhani said Iran was adopting “a strategy of deterrence in order to prepare for peace and security in Iran and the Middle East.”

“Our method of action is defense and not offense,” he said.

Russia announced earlier this week that it would supply the S-300s to Iran shortly, having delayed delivery for several years. The announcement prompted bitter protests from Israel, whose Prime Minister Benjamin Netanyahu telephoned President Vladimir Putin, in vain, to ask him to cancel the deal.

Israel fears the S-300s would complicate any military intervention as a last resort to thwart Iran’s nuclear drive. It also fears Iran could supply the missile defense systems to Syria or Hezbollah, diluting Israel’s air supremacy over Syria and Lebanon.

On Friday, President Barack Obama said he was surprised the Russians had held back from going through with the deal for as long as they had.

Rouhani also harshly criticized Saudi Arabia Saturday, warning that the Saudi royal family in Riyadh will harvest the hatred it is sowing in Yemen through its airstrike campaign.

Since March 26, the Saudi-led coalition has been attacking Shiite rebels known as Houthis and allied fighters loyal to Yemen’s ousted President Ali Abdullah Saleh. Iran supports the rebels but denies providing any military support.

“What does bombing the innocent … Yemeni people mean? What goals are you pursuing? Will killing children bring power to you? You planted the seeds of hatred in this region and you will see the response sooner or later,” Rouhani said. “Don’t bomb children, elderly men and women in Yemen. Attacking the oppressed will bring disgrace … for the aggressors.”

Iran’s Supreme Leader Ayatollah Ali Khamenei has already called the Saudi-led airstrikes in Yemen “genocide” and a “major crime.”

Iran has presented a four-point plan to end the conflict that includes humanitarian aid, dialogue and the formation of a broad-based Yemeni unity government after a proposed cease-fire was already rejected by Saudi Arabia.

Rouhani also accused Saudi Arabia of providing weapons and funding to terrorist groups in the Middle East.

“What does providing financial assistance and weapons to terrorists in Syria, Lebanon and Iraq mean,” he asked.

Iran is supporting both Syrian President Bashar Assad and the Iraqi government in its fight against Sunni Muslim extremists, including the Islamic State group. Tehran says Saudi Arabia and several other Middle East governments support the Islamic State group.

Prominent lawmaker Alaeddin Boroujerdi, who heads the parliamentary national security and foreign policy committees, predicted that Saudi Arabia will find itself trapped in the Yemeni “quagmire.”

“We are so sorry that today Saudi Arabia and (its allies) have placed themselves in a quagmire and leaving it will definitely not be an easy task,” he told reporters Saturday.
