The Leader made the remarks in a Tuesday meeting with the bereaved families of the martyrs of the terrorist attack deadly in the southern province of Fars late in October.
Ayatollah Khamenei said the United States was the creator and supporter of Daesh terrorist group, which claimed responsibility for the Shah Cheragh attack, adding that the criminal perpetrators and their founders are both complicit in the crime.
They are such inveterate liars and are so hypocritical that hoist the human rights flag in words but create dangerous terror groups in practice, Ayatollah Khamenei added.
The Leader said killing pilgrims is quite different from other acts of terror and brings further disgrace to the enemy.
A heavily-armed terrorist assaulted the well-known shrine at approximately 5:45 p.m. local time (1415 GMT) on October 26, just before the evening prayers, killing 15 pilgrims — including a lady and two children — and injuring at least 40 others.
The attacker opened fire indiscriminately on visitors within the shrine, according to the police commander of Fars province. The perpetrator was wounded and taken into custody by security personnel. He later succumbed to his wounds.
Soon afterward, Daesh claimed responsibility for the act of terror.
Ayatollah Khamenei also urged culture and art institutions to pay attention to the tragic incident and other historical issues and hand them over to future generations.
Iran’s young generation does not have enough information about past incidents such as the anti-Iran terrorist group best known as the Mujahedin-e-Khalq Organization (MKO), the Leader said.
Ayatollah Khamenei stated that cultural and media bodies should produce artistic products about the Shah Cheragh incident and other historical issues, noting that there are shortcomings in media works about issues pertaining to the history and events of the Islamic Revolution and the enemies’ crimes.
