At least 17 people were killed and 52 others injured in Tehran on Wednesday when gunmen mounted nearly simultaneous assaults on Iran's Parliament and the Mausoleum of the late founder of the Islamic Republic, Imam Khomeini.
The intelligence ministry said 41 suspects were arrested in Tehran, in the northwestern provinces of Kermanshah and Kurdistan, and in West Azerbaijan, near the borders with Iraq and Turkey.
Police late Sunday killed four ISIS suspects in the southern province of Hormozgan, the ISNA news agency on Monday reported police chief Azizollah Maleki as saying.
Alavi noted that about 43 terrorists were identified and arrested following the recent terrorist attack in the country, adding that some of them were in connection with the Tehran twin attacks and some of them were planning for terrorist acts in the future.
The Wednesday terrorist attacks on Iran's Parliament and the Mausoleum of Imam Khomeini left 17 people dead and 50 others injured.
While ISIS claimed responsibility, Iranian officials have also suggested Saudi Arabia may have played a role - and Iran's foreign minister called the official USA response "repugnant", after President Trump ended his expression of condolences for the victims with the message that "states that sponsor terrorism risk falling victim to the evil they promote".

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.
"In this bill, filled entirely with the support of terrorism, they have imposed sanctions on Iran's missile technology, IRGC and the Quds Force". The report called the detainees "elements of the Wahhabi IS group", and said they were involved in operations, communication and logistics for the local Islamic State cell.
On Tehran's enmity with Washington, the Iranian leader said "Some of the problems with the U.S. are essentially unresolvable as the US's problem with us has nothing to do with nuclear energy or human rights, their problem is with the principle of the Islamic Republic".
The Intelligence Ministry said its forces stormed several "safe houses" linked to the group in the country's northwest, according to state television.
Thousands gathered to commemorate the fallen, shouting "Death to Saudi Arabia" and "Death to America". Equipped with AK-47 assault rifles, handguns and suicide vests, the gunmen killed security guards and ordinary people before holding people hostage in the upper floors of the building.
