Days after the death of three-year-old Syrian refugee, Aylan Kurdi, shocked the world, 15 infants and children reportedly died on Sunday after their boat sank off the Greek coast while they were attempting to reach Europe. 

Four infants, and 11 children, including six boys and five girls, and 19 other people drowned near the Greek island of Farmakonisi when their wooden boat overturned, Reuters reported. 

The coastguard said the incident had led to the biggest death toll in the waters since the refugee crisis began. 

Sixty-eight others were rescued. 

Earlier this month, photos of Aylan Kurdi, whose family had fled their Syrian hometown of Kobane and were attempting to reach Greece from Turkey, sparked international outrage over the refugee crisis. 

The boy's lifeless body had washed up on a Turkish shore hours after he, his mother and brother died when their boat sank. 

Thousands of refugees have died this year while attempting to cross the Mediterranean Sea to Europe on dinghies and wooden boats.
