An operation to clear Europe’s biggest makeshift refugee camp is progressing without problems, Greek officials say. <br /><br /> Hundreds of riot police moved into the Idomeni camp with bulldozers at dawn on Tuesday, ordering residents to leave. <br /><br /> At least 8,000 people have been stuck at the site since March after the Greek-Macedonian border was closed. <br /><br /> Despite terrible living conditions, many of the migrants and refugees in the camp had previously resisted attempts by Greece’s government to get them to leave. <br /><br /> Most have now reportedly been bused to state-run centres further south. <br /><br /> At its peak in February, at least 12,000 people were stranded in the Idomeni camp having been prevented from continuing their journey further north.
