Relatives of the wildfire victims attend the memorial service for their loved ones at the seaside town of Mati, some 30 kilometers east of Athens, Greece, on July 21, 2019. The wildfires that devastated Mati in July 2018 left 102 dead, hundreds of damaged houses, many acres of charred down forest land and the entire Greek nation in a state of shock.
