Iran supreme leader: Attacks fuel hatred toward US, Saudis

On Thursday, Iran's Intelligence Ministry released photos of terrorist attackers in Tehran, saying they were linked to an ISIS ringleader killed a year ago in western province of Kermanshah.

According the official website of the ministry the attackers were affiliated with "Wahhabi and Takfiri" groups, which took part in ISIS crimes in Mosul city of Iraq and Raqqah in Syria.

Islamic State has claimed responsibility for the suicide bombings and gun attacks on parliament and the mausoleum of the Islamic Republic's founder, Ayatollah Ruhollah Khomeini, on Wednesday.

The intelligence ministry said there had been a third "terrorist" team that was neutralized before the attacks started.

On Thursday, Iran's Intelligence Minister Mahmoud Alavi said investigators were working to determine whether Saudi Arabia had a role Wednesday's attacks but said it was too soon to say if that was the case.

(CNN) - Iran has slammed US President Donald Trump's response to Wednesday's twin terror attacks in Tehran as "repugnant", as the death toll from the ISIS-claimed assaults rose to 16.

It then added, "We underscore that states that sponsor terrorism risk falling victim to the evil they promote".

"We express our condolences to the victims and their families, and send our thoughts and prayers to the people of Iran", she added.

"Repugnant WH [White House] Iranians counter terror backed by USA clients", Zarif tweeted.

"The Iranian people reject such US claims", Zarif said via Twitter.

The speaker claims to represent the "first battalion" of IS formed inside of Iran.

The attackers were armed with rifles and pistols and at least two blew themselves up with suicide vests, Iranian media reported.

Iran's powerful Revolutionary Guard indirectly blamed Saudi Arabia for the attacks. Both Iran and the Syrian government portray the Syrian war as a conflict against Western- and Gulf-sponsored terrorism. They've argued the deal only delayed Iran's pursuit of nuclear weapons and failed to allow the kind of inspections of its atomic sites that would guarantee Tehran was not cheating.

They have also undermined Tehran's belief that by backing offensives against Islamic State across the Middle East, it can keep the militant Sunni group away from Iran.

ISIS, which adheres to a puritanical strain of Sunni Islam, considers Shias heretics and has carried out numerous attacks against Shia civilians, in Iraq in particular.

On the streets of the capital Thursday, Iranians said they remained suspicious that Saudi Arabia had a hand in the attack.

Shojaei told state TV that "three of the victims are women".

In exchange of Iran rolling back its nuclear program, the United States and other world powers agreed to suspend wide-ranging oil, trade and financial sanctions that had choked the Iranian economy.

The Intelligence Ministry said its forces stormed several "safe houses" linked to the group in the country's northwest, according to state television.
