Powerful Earthquake Kills Hundreds in Turkey, Syria

A powerful earthquake struck the border between Turkey and Syria, causing significant damage and prompting rescue efforts. The earthquake led to the collapse of over 1700 buildings and a rising death toll. Oil flows to the Mediterranean port of Jahan were halted as a precaution, although no pipeline damage was reported. Turkey is in a highly active seismic zone, and this earthquake is considered the most powerful since 1999, possibly since 1939.
