AFP, ATHENS: At least seven children died when boats carrying migrants sank off Greece on Wednesday, as rescue workers battled to save more youngsters on the seashore in the latest desperate scenes in Europe’s refugee crisis. Three adults also died as four vessels went down on the dangerous sea crossing from Turkey and more than 200 people, many suffering hypothermia, were rescued from one sinking off the north coast of the Greek island of Lesbos. Images from Lesbos, a major entry point for the huge flow of migrants trying to get to Europe, showed doctors attempting to revive unconscious children on the island’s shoreline. Later in the evening, a drowned woman and the bodies of two children were found floating off the Greek island of Agathonisi, just a few kilometres from the Turkish coast.
