| 16 | IDOMENI, Greece (AP) - Police clashed Friday with thousands of migrants stuck at the border between Greece and Macedonia, waiting to continue long journeys into European Union countries where they hope to seek asylum. |
| 17 | Greece has seen a huge wave of migrants, 160,000 so far this year, many fleeing war and persecution in Syria and Afghanistan. |
| 18 | Most take rubber boats from Turkey to the Greek islands, then make their way north. |
| 19 | About 39,000 people, mostly Syrian refugees, have registered as passing through Macedonia in the past month, twice as many as the month before. |
| 20 | They previously encountered little resistance at the border, but the recent influx has overwhelmed Macedonian authorities who this week declared a state of emergency and stopped many from crossing. |
| 21 | On Friday, police fired stun grenades into a crowd of 3,000 migrants that made several attempts to charge them. |
| 22 | At least eight people were injured. |
