"Our Interior Ministry and Health Ministry, AFAD, provincial governorships, and all other institutions started their work rapidly.
"We are also coordinating our work after the (initial) earthquake. We hope that we will get through this disaster together as soon as possible and with the least damage, and we continue our work," he said.
Türkiye issued a level 4 alarm, which includes a call for international aid, AFAD said in a statement.
Following a discussion with the Turkish Foreign Ministry, AFAD also said that international assistance was called for through the Emergency Response Coordination Center (ERCC).
Besides rescue teams, blankets, tents, food and psychological support teams were also sent to the region.
After the initial earthquake, an "air aid corridor" was created by the Turkish Armed Forces to deliver search and rescue teams to the region.
"We mobilized our planes to send medical teams, search and rescue teams and their vehicles to the earthquake zone. We have maximized the readiness of our aircraft to provide the necessary transportation service," National Defense Minister Hulusi Akar said.
A large number of transport aircraft, including a Turkish Armed Forces A-400M, began to dispatch search and rescue teams and vehicles to the region. Ambulance planes are also using the air aid corridor, Akar added.
"The Turkish Armed Forces continues our efforts to determine damage and casualties. Unfortunately, we have three martyrs. There are also injured," he said.
He later announced that a naval personnel transport ship would dock at the port of Iskenderun in Hatay later in the night to carry those injured to hospitals in Mersin province, about 140 kilometers (87 miles) west.
Health Minister Fahrettin Koca said a sufficient number of teams from all 81 provinces are on duty in disaster areas and continue their search and rescue and health services.
