More than 4,300 dead in Turkey and Syria after strong quake

(CNN) ⸻ At least 2,921 people are dead and more than 15,800 injured in Turkey's Gaziantep province. In neighboring Syria, at least 1,451 people have died, including 711 in government-controlled areas. One of the strongest earthquakes to hit the region in a century shook residents from their beds. A series of aftershocks have reverberated throughout the day. Earthquakes of this magnitude are rare, with fewer than five occurring each year anywhere in the world. The World Health Organization activated its network of emergency medical teams in Turkey and Syria to assist those affected by the earthquake. Nearly 1,000 search and rescue volunteers have been deployed from Istanbul, along with dogs, trucks and aid. Gaziantep province has a number of small- and medium-sized cities, with a sizable refugee population. Some parts of Gaziantep seem to have been devastated, an analyst says. Video from Diyarbakir shows rescue workers frantically trying to pull survivors out of the rubble.
