Turkish President Recep Tayyip Erdogan on Tuesday declared a disaster zone in the 10 southeastern provinces affected by the devastating earthquakes, imposing a state of emergency in the region for at least three months.

Erdogan said 70 countries have offered to help with the search and rescue operations in Turkey and that his government plans to open up hotels in the southwestern resort city of Antalya to temporarily house people impacted by the disaster.

More than 8,000 people have been rescued in southeastern Turkey since a powerful earthquake and aftershocks struck the region, Turkish Vice President Fuat Oktay said at a press conference on Tuesday.

Some 24,000 first responders are on the ground, including more than 3,200 first responders from 14 other countries who traveled to Turkey to assist with the massive search and rescue effort following Monday’s quake. They are carefully combing through the wreckage and looking for survivors amid the 6,000 buildings that have been either damaged or destroyed, according to Oktay.

Monday’s massive earthquake and powerful aftershocks have killed at least 3,419 people and injured another 20,534 in southeastern Turkey, Turkish Vice President Fuat Oktay announced during a press conference on Tuesday.

Meanwhile, at least 1,603 were killed and 3,649 injured in both government- and rebel-controlled areas of northwestern Syria, according to combined figures from the Syrian Ministry of Health and the Syrian civil defense and medical group that operates in opposition-held areas, known as the White Helmets.

More than 24 hours after devastating earthquakes, ABC News reporters on the ground are witnessing the fevered effort to rescue survivors at a collapsed apartment building in southeastern Turkish city of Diyarbakir.

ABC News learned that crews had recently rescued a woman from what used to be an eight-story apartment building, where the top half now rests on three flattened floors below. The front wall had fallen away, exposing what used to be homes with furniture, pillows and air conditioning units.

In and around the collapsed building, there was a flurry of activity -- but then a moment when it all came to a grinding halt. Generators were turned off, everyone stopped talking and the block went silent. Search and rescue teams thought they may have found another survivor. It was quiet for several minutes, but then the urgent effort returns.

Rescuers continued working in the cold, wet weather while also facing the threat of aftershocks. None of that has deterred them. They know this is a race against time.

The United States is “ramping up” assistance to Turkey and Syria, White House spokesperson John Kirby said Friday.

“In Turkey, a USAID Disaster Assistance and Response Team is already on the ground. And two of our most highly trained urban search and rescue teams are conducting operations in support of Turkish rescue efforts in Adana -- one of the hardest-hit areas inside the country,” Kirby said. “These teams have nearly 200 personnel combined between them, specialized equipment and canine support dogs, as well.”

Kirby said they’ve been able to “expand their operational reach with the support of U.S. military Blackhawk helicopters” to try and get around the extensive damage to roads and bridges.

“To date, they have been able to cover more than 630 sites across Adana [in Turkey],” Kirby said. “In Syria, our humanitarian partners continue to urgently scale up response efforts to reach people in need. That work will include, or has included, chartered flights that are transporting essential medical supplies and teams distributing hot meals and other food.”

The United Nations and its partners have successfully completed two humanitarian convoys into northwest Syria, Kirby said. One partner delivered 14 additional truckloads of supplies through the Bab-al-Hawa Crossing on the Turkey-Syria border, “totaling now 20 trucks of critical medicines, food and water to people in need over the last two days,” he said.

Kirby said U.S. sanctions imposed on Syria “will not prevent or inhibit prohibiting humanitarian assistance.”
