Greek authorities have begun a second day moving people out of the sprawling Idomeni refugee camp on the country's northern border with Macedonia.
Some of those staying in Idomeni had already boarded two buses waiting to take them to other camps by the time police arrived.
More than 700 officers were deployed but no violence was reported in the operation that began at dawn on Tuesday in the camp of more than 8,000 people. Journalists have been banned from approaching the site.
Authorities said about 2,000 people were moved on Tuesday. The evacuation is expected to last several days.
