Islamic State claimed responsibility for attacks on Iran’s parliament and Ayatollah Khomeini’s shrine on Wednesday, the group’s state news agency AMAQ said.

“Fighters from Islamic state attacked Khomeini’s shrine and the Iranian parliament in Tehran,” the news agency said.

In another statement the news agency said the attacks on Khomeini’s shrine were carried out by two suicide bombers.

The two attacks happened almost simultaneously and killed up to seven people.

The attack on Iran’s parliament comes days after ISIS claimed responsibility of the London bridge attacks and that of Manchester where a concert was to be held.
