Syria air strikes: US threatens further military action against Syrian regime

Syrian ambassador Bashar Jaafari also said that his government viewed the strike as “illegal”,  motivated by “propaganda” and “unobjective data”.

Both Damascus and Moscow have denied the regime used chemical weapons in Khan Sheikhoun, maintaining that the casualties were caused by gases released after an al-Qaeda-affiliated ammunitions depot was hit by conventional munitions in a government air raid.

The shock US decision to launch a strike against a Syrian regime target has further complicated the already dazzlingly complex Syrian civil war.

The UN’s envoy to Syria, Staffan di Mistura, said on Friday that his office was in “full blown crisis management mode”, with three years of sustained peace efforts potentially on the line.

The White House has stressed that the 59 Tomahawk missiles launched at al Shayrat airbase – which a local resident described as causing “massive blasts” – were a “necessary and appropriate” warning shot in retaliation for the alleged chemical weapons attack.

Yet fears of further US direct military action – carried out without consultation from Congress – are building, both inside Syria and across the world.

“You will not be able to bomb your way to peace in Syria,” Senator Ben Cardin, the top Democrat on the Senate Committee on Foreign Relations, told CNN on Friday.

“Syrians must work out their problems,” Mr Cardin said. “President Assad must be held accountable for war crimes. He’s lost credibility as a leader. He must leave the presidency. This is not just what America thinks, but the international community.”

The new US administration had previously appeared content to let Turkey take the lead in peace negotiations with Russia, Iran and the Syrian government, focusing its military efforts in the country on defeating Isis and al-Qaeda rather than Mr Assad’s removal from power.

Since the fall of Aleppo in December 2016, and Mr Trump’s arrival in office, most Western players in Syria’s war have operated on the understanding that the best outcome rebel fighters can hope for is free elections in which the embattled ruler agrees to step down.

The strikes were cautiously welcomed by the US’s Western allies, including the UK, as a “proportionate” response to Mr Assad’s alleged use of chemical weapons.

While Mr Assad has acted with “impunity” and is “the greatest war criminal of all”, UK ambassador Matthew Rycroft told the Security Council, “a diplomatic solution must be found to the crisis”.

The long-term prospects for peace in Syria remain as grim as ever. While a ceasefire has technically been in place across Syria since the end of December between the moderate opposition and the government, both sides have continued to launch attacks, and a fifth round of peace talks in Geneva ended at an impasse at the end of last month.

The US, UK and French representatives to the UN on Thursday called for a vote on a new resolution which would impose sanctions on “those responsible” for the chemical attacks on Khan Sheikhoun.

Russia has used its position as a permanent member of the Security Council to veto similar action several times, most recently in February, and is likely to do so again in any new vote
