U.S. attack on Syria air base crosses 'red lines', say Assad allies

Amman: A joint command centre made up of the forces of Russia, Iran and militias supporting Syrian President Bashar Al Assad said the U.S. strike on a Syrian air base on Friday crossed "red lines" and it would respond to any new aggression and increase its support for its ally.
The United States fired dozens of cruise missiles at a Syrian air base on Friday from which it said a deadly chemical weapons attack had been launched earlier in the week, escalating the U.S. role in Syria and drawing criticism from Assad's allies including Russia and Iran.
"What America waged in an aggression on Syria is a crossing of red lines. From now on we will respond with force to any aggressor or any breach of red lines from whoever it is and America knows our ability to respond well," said the statement published by the group on media outlet Ilam al Harbi (War Media).
U.S. Secretary of State Rex Tillerson, meanwhile, blamed Russian inaction for helping fuel the chemical weapons attack it had reacted to, saying Moscow had failed to carry out a 2013 agreement to secure and destroy chemical weapons in Syria.
He said the United States expected Russia to take a tougher stance against Syria by rethinking its alliance with Assad because "every time one of these horrific attacks occurs, it draws Russia closer into some level of responsibility."
Russian President Vladimir Putin and Iran's Hassan Rouhani said in a phone call that aggressive U.S. actions against Syria were not permissible and violated international law, the Kremlin said on Sunday.
The two leaders also called for an objective investigation into an incident involving chemical weapons in Syria's Idlib and said they were ready to deepen cooperation to fight terrorism, the Kremlin said in a statement on its website.
Syrian army forces had been losing ground across the country until Russia intervened militarily in September 2015, propping up Assad and protecting its own interests in the region.
The joint command centre also said the presence of U.S troops in northern Syria where Washington has hundreds of special forces helping the Syrian Democratic Forces (SDF) to oust IS was "illegal" and that Washington had a long-term plan to occupy the area.The regional alliance said the U.S. cruise missile strikes on a Syrian base which Washington said was involved in a chemical attack that killed dozens of civilians would not deter their forces from "liberating" all of Syrian territory.
They also see Russia as a foreign occupier whose relentless aerial bombardment of rebel-held areas has led to thousands of civilian casualties. Some accuse Moscow of applying a "scorched-earth policy" that targets hospitals, schools and residential areas more than frontlines to break the resolve of the anti-Assad insurgency.
