While the world watches the war in Ukraine enter its third week, a bitter anniversary is being observed in Syria, where the bloody civil war is beginning its second decade.
The fighting has killed at least 400,000 Syrians and displaced more than half of the pre-war population of 21 million, with an estimated 6.7 million people internally displaced and 6.6 million refugees, mostly in neighboring countries such as Lebanon, Jordan, Turkey, and Iraq.
