Trump considering to introduce sanctions against Russia, Iran for supporting Syria

Syria's government denied it carried out any chemical attack on Khan Sheikhoun, and Russia's Defense Ministry said the toxic agents were released when a Syrian airstrike hit a rebel chemical weapons arsenal and munitions factory on the town's eastern outskirts.

Trump stated that, apart from the humanitarian reasons, he had struck at the Assad regime to uphold vital USA interests in deterring the use and spread of weapons of mass destruction. "Vladimir Putin and Hasan Rouhani spoke in favor of an objective, unbiased investigation of all the circumstances of the chemical weapons incident on April 4 in the Syrian province of Idlib".

These were not deployed in the US strike, but if used, such air defenses would radically alter Syria's aerial battlespace, where USA planes have largely flown with little fear of getting shot down.

USA military vessels pounded the Shayrat airbase with cruise missiles in response to a chemical weapons attack on a rebel-held Syrian village that killed over 80 people.

US Secretary of State Rex Tillerson said Russian Federation had failed to honor an agreement to to guarantee the elimination of Syria's chemical weapons.

The strikes also prompted a backlash from Russian Federation.

Turkey's Foreign Minister Mevlut Cavusoglu said Ankara sees the USA intervention in Syria as appropriate but not enough. United States ambassador to the UN Nikki Haley to UN says U.S. "prepared to do more" in Syria.

Skeptics noted that a confrontation with Russian Federation over Syria was well-timed for a president whose campaign is under investigation by the FBI and congressional committees for possible coordination with Moscow during the 2016 election. Assad accused the US of trying to boost the morale of "terror groups" in Syria.

On Friday, senior USA military officials were looking more closely at possible Russian involvement in the poison attack.

Saudi Arabia said the missile launch by Trump was the right response to "the crimes of this regime to its people in light of the failure of the worldwide community to stop it". He arrived earlier Tuesday to meet with Russian officials about the Syria civil war.

The two-day G-7 meeting of top diplomats from Italy, the United States, Germany, France, Britain, Canada and Japan is taking place under tight security in the historic city center.

The forces also pledged more support to the Syrian government and its army in the wake of the US missiles attack. Russia's Defense Ministry said that only 23 of the 59 missiles had reached their target.

President Hassan Rouhani earlier criticised his USA counterpart Donald Trump for the missiles fired early on Friday in response to the suspected chemical attack.

The hope, he said, is that "we can navigate a political outcome in which the Syrian people, in fact, will determine Bashar al-Assad's fate and his legitimacy".

Johnson called on Russian Federation, a key Assad ally, "to do everything possible to bring about a political settlement in Syria and work with the rest of the worldwide community to ensure that the shocking events of the last week are never repeated".
