ANKARA, Turkey—Turkish President Recep Tayyip Erdogan said Saturday that his country’s borders with Europe were open, as thousands of refugees gathered at the frontier with Greece.
Migrants played a cat-and-mouse game with Greek border patrols throughout the night and into Saturday, with some cutting holes in the fence only to be turned back by tear gas and stun grenades. Greek authorities also fired tear gas to repulse attempts by the crowd to push through the border.
