NURDAGI, Turkey (AP) — Rescuers raced against time early Wednesday to pull survivors from the rubble before they succumbed to cold weather two days after an earthquake tore through southern Turkey and war-ravaged northern Syria. The death toll climbed above 7,700 and was expected to rise further.

The last two days have brought dramatic rescues, including small children emerging from mounds of debris more than 30 hours after Monday’s pre-dawn quake. But there was also widespread despair and growing anger at the slow pace of rescue efforts in some areas.

“It’s like we woke up to hell,” said Osman Can Taninmis, whose family members were still beneath the rubble in Hatay, Turkey’s hardest-hit province. “Help isn’t coming, can’t come. We can’t reach anyone at all. Everywhere is destroyed.”

In Syria, residents found a crying newborn still connected by the umbilical cord to her mother, who was dead. The baby was the only member of her family to survive a building collapse in the small town of Jinderis, relatives told The Associated Press.

Search teams from nearly 30 countries and aid pledges poured in. But with the damage spread across several cities and towns — some isolated by Syria’s ongoing conflict — voices crying for help from within mounds of rubble fell silent.

Monday’s magnitude 7.8 quake and powerful aftershocks cut a swath of destruction that stretched hundreds of kilometers (miles) across southeastern Turkey and neighboring Syria. The shaking toppled thousands of buildings and heaped more misery on a region wracked by Syria’s 12-year civil war and refugee crisis.

Turkey is home to millions of refugees from the war. The affected area in Syria is divided between government-controlled territory and the country’s last opposition-held enclave, where millions rely on humanitarian aid to survive.

Unstable piles of metal and concrete made the search efforts perilous, while freezing temperatures made them ever more urgent, as worries grew about how long trapped survivors could last in the cold. Snow swirled around rescuers in parts of Turkey.

The scale of the suffering — and the accompanying rescue effort — were staggering.

Many survivors in Turkey have had to sleep in cars, outside or in government shelters.

“We don’t have a tent, we don’t have a heating stove, we don’t have anything. Our children are in bad shape. We are all getting wet under the rain and our kids are out in the cold,” Aysan Kurt, 27, told the AP. “We did not die from hunger or the earthquake, but we will die freezing from the cold.”

Adelheid Marschang, a senior emergencies officer with the World Health Organization, said up to 23 million people could be affected in the entire quake-hit area, calling it a “crisis on top of multiple crises.”

Turkish President Recep Tayyip Erdogan said 13 million of the country’s 85 million people were affected, and he declared a state of emergency in 10 provinces. More than 8,000 people have been pulled from the debris in Turkey, and some 380,000 have taken refuge in government shelters or hotels, authorities said.

But authorities faced criticism from residents of hard-hit Hatay, sandwiched between Syria and the Mediterranean Sea, who say rescue efforts have lagged. Erdogan’s handling of the crisis could weigh heavily on elections planned for May, and his office has already dismissed the criticism as disinformation.

Nurgul Atay told The Associated Press she could hear her mother’s voice beneath the rubble of a collapsed building in the Turkish city of Antakya, the capital of Hatay province. But rescuers did not have the heavy equipment needed to rescue her.

“If only we could lift the concrete slab, we’d be able to reach her,” she said. “My mother is 70 years old, she won’t be able to withstand this for long.”

Health Minister Fahrettin Koca said 1,647 people were killed in Hatay alone, the highest toll of any Turkish province. At least 1,846 people had been rescued there as of Tuesday evening, he said. Hatay’s airport was closed after the quake destroyed the runway, complicating rescue efforts.

In Syria, meanwhile, aid efforts have been hampered by the ongoing war and the isolation of the rebel-held region along the border, which is surrounded by Russia-backed government forces. Syria itself is an international pariah under Western sanctions linked to the war.

Volunteer first responders known as the White Helmets have years of experience rescuing people from buildings destroyed by Syrian and Russian airstrikes in the rebel-held enclave, but they say the earthquake has overwhelmed their capabilities.

Mounir al-Mostafa, the deputy head of the White Helmets, said they were able to respond efficiently to up to 30 locations at a time but now face calls for help from more than 700.

“Teams are present in those locations, but the available machinery and equipment are not enough,” he said, adding that the first 72 hours were crucial for any rescue effort.

The United Nations said it was “exploring all avenues” to get supplies to the rebel-held northwest.

U.N. spokesman Stephane Dujarric said the road leading to the Bab al-Hawa border crossing — the only terminal through which U.N. aid is allowed to enter the rebel-held area — was damaged by the quake, disrupting deliveries.

Dujarric said the U.N. was preparing a convoy to cross the conflict lines within Syria.

The U.N. already delivers aid across conflict lines to the rebel-held enclave. But it can’t move the quantities needed because of difficulties in arranging convoys with opposing parties, making aid deliveries from Turkey critical.

Syrian President Bashar Assad’s government has pressed for years for all humanitarian aid to be sent from within Syria, including to the opposition-held enclave. The U.N. has increased cross-conflict line deliveries but not enough for the millions in need.

Turkey has large numbers of troops in the border region and has tasked the military with aiding its rescue efforts, including setting up tents for survivors and a field hospital in Hatay province.

A navy ship docked Tuesday at the province’s port of Iskenderun, where a hospital collapsed, to transport people in need of medical care to a nearby city.

A large fire at the port, caused by containers that toppled over during the earthquake, sent thick plumes of black smoke into the sky. The Defense Ministry said the blaze was extinguished with the help of military aircraft, but live footage broadcast by CNN Turk showed it was still burning.

Vice President Fuat Oktoy said at least 5,894 people have died from the earthquake in Turkey, with another 34,810 injured.

The death toll in government-held areas of Syria has climbed to 812, with some 1,400 injured, according to the Health Ministry. At least 1,020 people have died in the rebel-held northwest, according to the White Helmets, with more than 2,300 injured.

The region sits on top of major fault lines and is frequently shaken by earthquakes. Some 18,000 were killed in similarly powerful earthquakes that hit northwest Turkey in 1999.
