Iran's intelligence ministry identified the ringleader and bomb-maker behind the twin suicide bombings in Iran last week. The attack, claimed by the Islamic State group, had a death toll of at least 94. The main suspect, Abdollah Tajiki, a Tajik national, entered Iran in mid-December and left two days before the attack. One of the bombers, Bozrov, had Tajik and Israeli nationality and received training from IS in Afghanistan. Iranian authorities have arrested 35 people with links to the bombings.
