The US has reportedly begun an investigation into whether Russia is linked to the suspected chemical attack in Syria’s Idlib, which Washington claims was carried out by Damascus. It comes after Russia condemned the US strike on a Syrian air base, which killed six people.

The AP report comes amid an array of reactions to the early Friday Tomahawk cruise missile strike on the Syrian army’s Shayrat airfield near Homs, which US President Donald Trump said he ordered after Damascus “used banned chemical weapons.”

Despite no investigation into the incident, which Russia and Syria said coincided with the bombing of a rebel warehouse storing munitions and toxic substances allegedly used in the production of shells used in Iraq and in some previous gas attacks in Syria, the US and its western allies have jumped to conclusions that Syrian President Bashar Assad bears responsibility for “chemical attack.”

US Ambassador to the UN Nikki Haley, commenting on the attack at an emergency meeting of the UN Security Council, claimed that the US actions “were fully justified” while adding Washington is “prepared to do more,” but “hope[s] that will not be necessary.”

Moscow has decried the US bombing of Syria. Kremlin spokesman Dmitry Peskov said President Putin “regards the strikes as aggression against a sovereign nation,” in violation of international law, conducted “under an invented pretext.”

Russia’s Prime Minister Medvedev said that the attack was conducted “on the verge of a military clash” with Russia and showed that Trump has already bowed down to the establishment he once used to harshly criticize.

Russian deputy acting envoy to the UN Vladimir Safronkov also believes that the US is “afraid” of “real investigation” into the incident which might show that president Assad did not use chemical weapons.
