78 people have died and more than 100 have been rescued after their fishing boat sank off southern Greece.
Greece says it is one of its biggest ever migrant tragedies, and has declared three days of mourning.
Authorities say their offers of aid were refused but they are facing claims of not doing enough to help.
The boat went down about 80km (50 miles) south-west of Pylos after 02:04 on Wednesday morning local time, according to the Greek coastguard, which lowered an earlier confirmed death toll of 79 to 78.
