A search and rescue operation is ongoing off the coast of an eastern Greek island after a rubber dinghy carrying migrants sank, leaving seven people dead and 23 rescued. The search is focused on finding a missing child, as survivors reported a total of 31 people on board. Greece is a main entry point into the EU for migrants fleeing conflict and poverty, with many making the dangerous journey from the Turkish coast to Greek islands. Fatal accidents are common due to unseaworthy vessels and bad weather.
