TEHRAN: Iran summoned diplomats from three European countries over an attack on an army parade near the Iraqi border which killed at least 29 people, state-run media said on Sunday.

The Dutch and Danish ambassadors and the British charge d’affaires were “informed of Iran’s strong protests over their respective countries’ hosting of some members of the terrorist group” who carried out the attack, official news agency IRNA said, told AFP.

The Islamic State (IS) jihadist group claimed responsibility for the rare assault, which saw gunmen spray a crowd with gunfire in the southwestern city of Ahvaz. Iranian officials have blamed “a foreign regime” backed by the United States
