ANKARA (REUTERS) - Iran's Revolutionary Guards say Saudi Arabia was behind twin attacks in Teheran on Wednesday (June 7) that killed at least 12 people and injured 43, a statement published by the Guards said.

"This terrorist attack happened only a week after the meeting between the US president (Donald Trump) and the (Saudi) backward leaders who support terrorists. The fact that Islamic State has claimed responsibility proves that they were involved in the brutal attack," said the statement from the elite unit, published by Iranian media.

The attacks were the first claimed by ISIS, a hardline Sunni Muslim militant group, in the tightly controlled Shi'ite Muslim Iran.
