Russia’s top diplomat has warned that the situation in Syria was spiraling out of control after an unclaimed missile strike hit an air force base overnight in the central Homs province. Despite Moscow’s warnings, President Donald Trump vowed to decide as early as Monday evening on whether or not to launch his own attack.

Not long after declaring his intention to soon withdraw troops from Syria, Trump said Monday he was considering a major escalation in response to reports that the Syrian government used chemical weapons on one of the final rebel-held pockets outside of the Syrian capital of Damascus. The Republican leader condemned the alleged use of toxic gas and confirmed that “nothing was off the table” in terms of retaliation.

“If it’s Russia, if it’s Syria, if it’s Iran, if it’s all of them together, we’ll figure it out and we’ll know the answers quite soon. So we’re looking at that very, very strongly and very seriously,” Trump said at a Cabinet meeting. When asked later about Russian President Vladimir Putin’s potential role, Trump said that “everybody’s going to pay a price—he will, everybody will.”

The evacuations came shortly after reports that the Syrian military used toxic gas against rebels and civilians, a charge that the Syrian and Russian governments have denied. YOUSSEF KARWASHAN/AFP/Getty Images

While Trump said he would “be making some major decisions over the next 24 to 48 hours” or even “later today,” his Russian counterpart dismissed Western “provocations and speculations” that the Syrian military was behind a chemical attack in a phone call with German Chancellor Angela Merkel, according to a Kremlin statement. Top Russian political and military officials have previously warned that they may take retaliatory military action if the U.S. attacked Syria’s armed forces, especially if it endangered Russian personnel.

In another press conference Monday, Russian Foreign Minister Sergey Lavrov questioned Trump’s intention to take his troops out of Syria and accused the U.S. of trying to prolong its stay in a country that has rejected the Pentagon’s military presence. He also warned of the consequences of Sunday night’s airstrikes, which Moscow has officially blamed on Israel.

“The U.S. is taking steps…to establish a foothold there for a very long time—experts agree on this,” Lavrov said during a press conference, not yet confirming the Kremlin’s suspicion that Israel was behind the attack on Syria’s T-4 airbase, also know as Tiyas or Tayfour.

“Washington denied that these strikes were delivered by members of the coalition,” Lavrov noted. “This once again shows that it is becoming too dangerous in Syria. Players emerged there whom no one had invited and who invited there themselves.”

The strikes came shortly after Trump promised there would be a “big price…to pay” for the alleged chemical weapons attack in the besieged suburb of Douma, where Moscow has attempted to broker negotiations between the Syrian government and Islamist rebel group Jaysh al-Islam. Many local reports initially suggested that the missiles fired at T-4 air base came from U.S. warships in the Mediterranean, as they did in response to another alleged chemical weapons attack nearly exactly one year ago. The U.S. denied this.

Official sources, including those in Russia, Iran, Syria and Lebanon, have said Israeli jets shot the missiles after breaching Lebanese airspace.

Israel has yet to comment on the accusations, but has occasionally struck suspected Iran-backed Lebanese Shiite Muslim movement Hezbollah positions in neighboring Syria throughout the country’s seven-year civil war. Iranian officials were reportedly present at the T-4 airfield and Iran confirmed Monday that four of its military advisers were killed, according to the semi-official Fars News Agency.​
