ATHENS, Greece (AP) — Greece's coast guard says it has picked up nearly 2,500 migrants from the sea in dozens of search and rescue operations over the weekend, part of a relentless flow of people heading for the safety of Europe after facing war and poverty in the Middle East, Africa and Asia.

The coast guard said Monday it had rescued 2,492 people in 70 operations off the eastern islands of Lesbos, Chios, Samos, Agathonissi, Farmakonissi, Kos and Symi from Friday morning until Monday morning.

Separately, it said a coast guard patrol boat rescued another 13 people spotted in the water near the port of Chios by a local boat. One person was recovered unconscious and transported to a hospital. The circumstances of the incident were not immediately clear.
