The unlikely rescue, 91 hours after a powerful earthquake in the Aegean Sea, sent a swell of joy across Turkey at a moment when the country was grieving from one of its worst tragedies in years. The earthquake that occurred off the coast of Izmir on Friday has killed more than 100 people in Turkey, many of whom were in buildings and apartment blocks that buckled and collapsed when the temblor struck. Two teenagers on a Greek island, near the quake’s epicenter, were also killed.
