Tasnim News Agency, affiliated with the Islamic Revolutionary Guard Corps (IRGC), published new details about one of the attackers of the Shah Cheragh shrine in Shiraz city.

According to this news agency, the attacker, Rahmatullah Nowrozov is a citizen of Tajikistan, who joined ISIS in Turkey and then, trained for three months in Afghanistan.

On Wednesday, Tasnim reported that Nowrozov, whose organisational name is "Salman Aslamyar", contacted one of his ISIS contacts through the internet.

Tasnim added that the attacker has finished "ISIS training for terror operations" in Afghanistan for about three months and then, entered Iran to wage the terror attack.

According to Iranian media reports, two people were killed and at least seven people were injured in the attack on Shah Cheragh shrine in Shiraz.

On Tuesday, Yadullah Boali, the commander of the IRGC Fajr Fars Corps, told reporters that the attacker was part of a “network” which, according to Boali, "operates in several countries”.

The Iranian official added that more than 10 people have been arrested in connection with the Shah Cheragh attack.

Earlier, a group of UN experts said that ISIS is the most serious terrorist threat in Afghanistan and the region and has increased its operational capabilities.

After the Taliban’s dominance in Afghanistan, several neighbouring and Central Asian countries have always expressed concern about the presence of terrorist groups, especially ISIS, in Afghanistan.

Although Taliban officials claim that ISIS has lost its operational capability in Afghanistan, they have repeatedly announced attacks against ISIS fighters in the past months.

ISIS has also claimed responsibility for several attacks against Taliban officials in the past months.
