TEHRAN (CBSNewYork/AP) — Iranian police say they have five suspects in custody in connection to the twin terror attacks that killed at least a dozen people in the capital city of Tehran.

Gunmen and suicide bombers targeted parliament and the nearby shrine of Ayatollah Ruhollah Khomeini, a key figure in the founding of Iran’s Islamic Republic, in Tehran on Wednesday. The Islamic State terror group has since claimed responsibility for the bloodshed.

Twelve people were killed and dozens more wounded in the attacks, according to an Iranian state-run news website.


The attack on parliament, which was in session at the time, lasted more than three hours.

“It’s definitely surprising,” Middle East expert from Chatham House Sanam Vakil said. “Iran has been one of the countries that has not experienced a terror attack from ISIS to date, and they have very much championed that.”

All entrance and exit gates at parliament were closed, and lawmakers and reporters were ordered to remain in place inside the chamber as police surrounded the building and gunfire could be heard from outside.

Four attackers were killed.
