Rescue teams and emergency supplies have begun arriving from around the world after the worst earthquake since 1999 struck the Turkish-Syrian border. The death toll has passed 5,000, tens of thousands more injured and hundreds of thousands displaced from the 7.8 magnitude earthquake and 7.5 magnitude aftershock hours later. Turkish President Recep Tayyip Erdogan has declared a state of emergency in the region. The United Nations said is was exploring all options to get relief supplies into northwestern Syria, which has already been devastated by the 12-year long Syrian Civil War and is home to an estimated 4 million people.
