U.S. President Donald Trump announced last week that American troops will pull out of Syria, a decision that caught U.S. allies Kurds by surprise.

The Syrian military announced Friday that they have entered the key Kurdish-held town in the country after the main Syrian Kurdish militia invited the government to take control to prevent a Turkish attack.

Lavrov, who was hosting the Jordanian foreign minister on Friday, told reporters that Moscow hopes to receive “concrete explanations” from U.S. officials of the reason behind the decision to pull out, AP reported.

Lavrov also said that “it appears that Washington wants to shift the responsibility” on other partners in the anti-Islamic State group coalition who will remain on the ground.
