Turkey’s President Recep Tayyip Erdogan on Saturday threatened to let thousands of refugees cross into Europe and warned that Damascus would “pay a price” after dozens of Turkish troops were killed inside Syria.

Around 13,000 migrants have gathered along the Turkish-Greek border, the International Organization for Migration (IOM) said late Saturday.

Earlier in the day, Greek police clashed with several thousand migrants, as they hurled rocks at security forces firing tear gas across the frontier.

Turkey and Russia meanwhile, who back opposing forces in the Syria conflict, held talks to defuse tensions after an air strike killed the Turkish troops, sparking fears of a broader war and a new migration crisis for Europe.
