The poison gas attack, blamed on the Syrian regime-who Russian Federation backs in the ongoing civil war in the country-sparked an aggressive response from the U.S., the United Kingdom, and France who are all opposed to President Bashar al-Assad and Moscow's support for him.
The United States, Russia, Syria, and Iran have all said that a pre-dawn air raid targeting the Iran-operated Tayfur (or "T4") airbase in Syria's central Homs province on Monday was carried out by Israel.

"We will stand by Syria's government against any foreign aggression", Velayati said, adding that Tehran backs Damascus in its fight against the USA and Israel.
Damascus denied its forces had launched any chemical assault and Russian Foreign Minister Sergei Lavrov said such allegations were false and a provocation.
Israel has a longstanding policy of refusing to comment on alleged military actions beyond the West Bank and Gaza Strip.
Velayati also said that there had been no chemical attack in the southern Syrian city of Douma over the weekend, as Western countries claimed.
The assessment also suggested that a nerve agent was used in the suspected poison attack, but further evidence was needed to determine the type of agent, USA government sources told the news agency. "Iran backs Syria in its fight against America and the Zionist Regime (Israel)", Ali Akbar Velayati told state TV during his visit to eastern Ghouta in Syria. Israel has taken out several strikes from Syria previously, several directed toward stopping exactly what it states is now a military buildup by Iran and its regional ally, Hezbollah, and the Syrian-Israeli border.
