A total of 28 bodies have been pulled from the sea off Greece after a boat carrying scores of migrants capsized on Sunday, the coastguard said.

Their stricken boat sank off the island of Farmakonisi in the southern Aegean Sea where a search and rescue effort is under way.  

A dead child was among those found early Sunday, while 68 people were rescued and a further 29 managed to swim to a beach on the island, the coastguard said.
