Iran's Revolutionary Guard strikes Syria for Tehran attacks

The attacks marked the first time that ISIS, a Sunni Muslim group fighting Iranian-backed militias in Syria, has claimed responsibility for an attack in Iran.

"I think (Israel) understood the message ... it now has to worry" about every move it makes, Sheikh Hussein al-Islam, an advisor to Iranian Foreign Minister Mohammad Javad Zarif, said in an interview with the Al-Miyadin TV station. The parallel offensives points to an escalation between forces which back Syrian President Bashar al-Assad, such as Iran, and the USA which supports rebel groups.

Iran's missile strike at ISIS Sunday in retaliation for the attacks in Tehran was a flop, the Times of Israel reports.

"International and regional supporters of the terrorists must realise the warning message of the missile operation".

Abadi is on a regional tour that started in Saudi Arabia and will include a stop in Kuwait. Iranian officials complained the new sanctions violate the spirit of the Joint Comprehensive Plan of Action, otherwise known as the Iran nuclear deal, however, ballistic missiles are not included in the agreement.

Analyst Foad Izadi said the strike was meant to convey several messages.

The launch takes place just a couple of hours after Iran's Supreme leader said "they can not slap us in the face".

IDF Chief of Staff Gadi Eisenkot also downplayed the significance of the Iranian strike.

According to Ya'ari, three of the seven missiles did not even reach Syrian territory, and instead landed in Iraq. The two countries support opposite sides in the conflicts in Syria and Yemen.

Sunday's strike came amid rising tensions between Riyadh and Tehran.

If this claim was true, it would be the first example of Iran using mid-range ballistic missiles, needed to travel the 400-mile distance, since the end of the Iran-Iraq war.

"Firing these missiles from 600 or 700 kilometres (370 or 430 miles) away onto a small building. demonstrates Iran's capacity and intelligence capabilities" against militant groups, he said.

"If we decide to target a location with missiles, this decision falls within the field of national security", said Rouhani. The officials spoke on condition of anonymity because they were not authorized to speak to reporters.

The Iranian Revolutionary Guards, said its military launched missiles into eastern Syria yesterday, targeting ISIS militants.
