At least 25 civilians, including 10 children and four women, were killed on Sunday in Russian and Syrian government airstrikes on the Syrian city of Idlib and rural Aleppo, the White Helmets announced Monday.

At least 25 people were killed in northwestern Syria in air strikes carried out by the Syrian government and Russia, the Syrian opposition-run rescue service known as the White Helmets said early on Monday.

Assad’s regime seemingly came out of nowhere, and as Aleppo fell to Turkish-backed rebels in a matter of days, the Syrian president reportedly flew to Moscow.
