Iran has arrested 26 foreign nationals over their alleged involvement in a deadly attack claimed by ISIS on a shrine, the intelligence ministry said Monday.
At least 13 people were killed on October 26 in an armed attack on the Shah Cheragh mausoleum in Shiraz, according to an official toll.
"The intelligence ministry has identified and arrested all agents involved in the terrorist operation in Shiraz," said a statement published on the ministry's website.
According to the statement, the 26 are from Azerbaijan, Tajikistan and Afghanistan.
They were arrested in the provinces of Fars, Tehran, Alborz, Kerman, Qom and Razavi Khorasan, as well as along Iran's "eastern border", AFP quoted the ministry as saying.
The perpetrator of the attack in Shiraz, identified by the intelligence ministry as Sobhan Komrouni, died of wounds sustained while he was being arrested.
The ministry said he was "a Tajik national" known as Abu Aisha.
It added that the main coordinator of attacks in Iran, an Azeri national, was also arrested, having entered the country through Tehran's international airport from Baku.
He had been in contact with an ISIS network abroad after arriving in Tehran, it added.
On October 31, the ministry announced that several others had been arrested, including an "operational support element" identified Monday as Mohammed Ramez Rashidi, an Afghan national.
