Greek rescuers are searching for people trapped after a four-storey apartment block collapsed in Athens.
Four people who were earlier reported trapped had been found and were safe, but the operation in the Petralona area continued, the fire brigade said on Tuesday.
Crew with rescue dogs searched the rubble while other forces were on standby, the service said in a statement.
It was not clear what caused the collapse of the building, which had seven apartments.
Construction work was under way in an adjacent building, the fire brigade said.
