Greece arrests five over Lesbos migrant camp blaze
Most of the 12,000 who fled the fire on the Greek island last week are still sleeping rough.
About 800 of more than 12,000 migrants and refugees who fled an inferno at a camp on the Greek island of Lesbos last week have been rehoused in a temporary structure.
The Greek migration ministry said 21 had tested positive for coronavirus and had been moved into isolation.
The tents are near the overcrowded Moria camp destroyed by the fire.
Meanwhile off Crete, Greek rescuers saved 56 migrants from a capsized boat but two children and a woman drowned.
Their bodies were recovered 12 nautical miles (14 miles) off Crete's eastern coast and it is not yet clear if there were more victims.
The Greek coastguard service said four vessels and two helicopters took part in the search late on Monday, amid strong wind.
