'Islamic State' claims responsibility for bombings in Iran

"Earlier, Iran expert at United Against Nuclear Iran, Kasra Aarabi, told DW, 'that attack itself certainly has all the hallmarks of ISIS operations in Iran.'

He said that would suit the government in Tehran.

'It is likely that the regime will blame ISIS that will enable the [Islamic Revolutionary Guard Corps] IRGC to respond,' he said, 

'It also domestically has given the regime a pretext to further clamp down on the Iranian people,' Aarabi added."
