Thousands of displaced residents of Idlib province in northwest Syria—under a Russian-backed bombardment by the Assad regime, which has killed about 300 over the past month and displaced more than 300,000—marched on the sealed Turkish border on May 31, demanding entry or international action to stop the bombing. With more than 3.6 million refugees already in Turkey, Ankara's authorities have blocked any further entries since 2016. But the regime bombing campaign, and accompanying a ground offensive that has shattered a so-called "demilitarized zone," now threatens a "humanitarian catastrophe," in the words of the United Nations. Abou al-Nour, an administrator at the overcrowded Atmeh camp, told Reuters that more than 20,000 families are now sleeping in an olive grove near the border. "They don't have any shelter or water, and this is beyond our abilities. We are doing all we can," he said.

One spokesman said, "These civilians came here today to tell the world, if you cannot save us, we will break the border and come to Europe to find a safer place to live."
