The Iran's Revolutionary Guards had blamed Saudi Arabia for Wednesday's attacks. The country's Supreme Leader said the attacks will add to the hatred that Iranians harbor toward the U.S. and Saudi Arabia.
Iran has arrested nearly 50 people in connection with the attacks in its capital that killed 17 people last week, officials said.
Khamenei said Iran had no intention of normalising ties with the United States."The American government is against an independent Iran".
"We should accept that a line comprising terrorists and the countries backing them, which are being led by the United States and Saudi Arabia, has formed against our people", Larijani said. The comments come just a day after Alavi said investigators were working to determine whether Riyadh had a hand in the attacks.
Earlier, Brigadier General Hossein Salami, IRGC deputy commander, said that Iran will "take revenge" for the attacks.
This is especially concerning since American Senators described Iran as the main supporter of terrorism, and the recent Tehran attacks proved Iran is tasting its own medicine.
"We will prove once again that we will crush the enemies' plots with more unity and more strength." . The twin assault claimed 17 lives when four armed assailants raided the country's Parliament while a suicide bomber struck at the Imam Khomeini Mausoleum. The legislation would impose new sanctions on Iran over its defense missile program, support for resistance movements and claims of human rights violations against the country.
At least some of the attackers reportedly disguised themselves by wearing women's clothing, using guns and explosives to cause mayhem at the mausoleum and parliament, or Majlis. Everything went according to plan, it was peaceful, it was progressive, she said.
