[Greek fisherman Valamios, a Nobel Peace Prize nominee, is seen onboard his motorboat at the sea, near the Skala Sikamias village on the island of Lesbos]By Karolina Tagaris LESBOS, Greece (Reuters) - For months Greek fisherman Stratis Valamios would steer his boat out to sea, only instead of fish, he pulled out people. Day after day, rubber boats packed with refugees and migrants would attempt the short but dangerous crossing to Greece from Turkey, even as winter set in and the seas turned rough and winds grew violent. "It was like a war zone," Valamios, now a co-nominee for the Nobel Peace Prize, said of his tiny seaside village of Skala Sikamnias on Lesbos, the island where more than 800,000 people escaping war and conflict in the Middle East and beyond arrived in 2015.
