More than 15,000 people have now been confirmed dead following the devastating earthquake in Turkey and Syria.
Rescuers have been seen clawing through rubble with their bare hands in the past few days amid sub-zero temperatures and snow storms in the region.
Officials say 12,391 people have died in Turkey, with a figure of 2,992 reported in Syria.
The powerful 7.8 magnitude earthquake shook southern Turkey and northern Syria early Monday, razing buildings to the ground and trapping thousands beneath the rubble. .
Rescue and recovery efforts have been hampered by a number of aftershocks and tremors, which some experts have warned may last weeks or even months.
Another earthquake with the magnitude of 7.5 hit Turkey’s south just hours after the first, with a third following later in the week.
Thousands of specialists from across Europe, Albania, Montenegro, Jordan and China have since offered their services to boost the 24,400 search and rescue teams already deployed by Turkey.
War-ravaged Ukraine also pledged an 87-strong team to help out, while Qatar offered 10,000 container shelters for people left homeless.
They were being transferred to the worst-hit provinces of Hatay, Kahramanmaras and Adiyaman across Turkey.
Around 380,000 survivors are sheltering in government dormitories or hotels in Turkey.
Experts said on Wednesday that the survival window for those trapped under the rubble or otherwise unable to obtain basic necessities was now closing rapidly - but said it was too soon to abandon hope.
Steven Godby, a natural hazards expert at Nottingham Trent University in England said: "The first 72 hours are considered to be critical"
"The survival ratio on average within 24 hours is 74%, after 72 hours it is 22% and by the fifth day it is 6%."
