Amid calls for the government to send more help to the disaster zone, President Recep Tayyip Erdogan was to travel to town of Pazarcik, the epicenter of the quake, and to the worst-hit province of Hatay on Wednesday.

Nearly two days after the magnitude 7.8 quake struck southeastern Turkey and northern Syria, rescuers pulled a 3-year-old boy, Arif Kaan, from beneath the rubble of a collapsed apartment building in Kahramanmaras, a city not far from the epicenter.

With the boy's lower body trapped under slabs of concrete and twisted rebar, emergency crews lay a blanket over his torso to protect him from below-freezing temperatures as they carefully cut the debris away from him, mindful of the possibility of triggering another collapse.

But such stories were few more than two days after Monday's pre-dawn earthquake, which hit a huge area and brought down thousands of buildings, with frigid temperatures and ongoing aftershocks complicating rescue efforts.

As many as 23 million people could be affected in the quake-hit region, according to Adelheid Marschang, a senior emergencies officer with the World Health Organization, who called it a "crisis on top of multiple crises."

Turkey's disaster management agency said the country's death toll had risen to 7,108, bringing the overall total to 9,638, including fatalities reported in neighboring Syria, since Monday's earthquake and multiple aftershocks.
