A 7.8-magnitude earthquake hit Turkey and Syria early on Monday, killing hundreds of people as they slept, levelling buildings and sending tremors that were felt as far away as the island of Cyprus, Egypt and Iraq.
One of the largest quakes to strike Turkey in a century wiped out entire sections of major cities in a region filled with millions of people who have fled the civil war in Syria and other conflicts.
The head of Syria’s National Earthquake Centre, Raed Ahmed, told pro-government radio that this was “historically, the biggest earthquake recorded in the history of the centre”.
At least 245 people died in government-controlled parts of Syria, as well as the northern areas held by pro-Turkish factions, according to the health ministry and a local hospital.
At least 284 people also died in Turkey, Vice President Fuat Oktay said on Monday, adding that more than 2,300 people had been injured and that search and rescue work was continuing in several major cities.
Shocked survivors in Turkey rushed out into the snow-covered streets in their pyjamas, watching rescuers dig through the debris of damaged homes.
“Seven members of my family are under the debris,” Muhittin Orakci, a stunned survivor in Turkey’s mostly Kurdish city of Diyarbakir, told AFP.
“My sister and her three children are there. And also her husband, her father-in-law and her mother-in-law.”
The rescue was being hampered by a winter blizzard that covered major roads in ice and snow. Officials said the quake made three major airports in the area inoperable, further complicating deliveries of vital aid.
The quake struck at 04:17 am local time (0117 GMT) at a depth of about 17.9 kilometres (11 miles) near the Turkish city of Gaziantep, which is home to around two million people, the US Geological Survey said.
Turkey’s AFAD emergencies service centre put the first quake’s magnitude at 7.4, adding that it was followed by dozens of aftershocks.
Turkish President Recep Tayyip Erdogan, who will be under intense pressure to oversee an effective response to the disaster heading to a tightly-contested May 14 election, conveyed his sympathies and urged national unity.
“We hope that we will get through this disaster together as soon as possible and with the least damage,” the Turkish leader tweeted.
US National Security Advisor Jake Sullivan said Washington was “profoundly concerned”.
“We stand ready to provide any and all needed assistance,” Sullivan said.
Additional offers of help poured in from the European Union, Russia, Italy and Turkey’s historic rival Greece, whose relations with Ankara have suffered from a spate of border and cultural disputes.
Ukrainian President Volodymyr Zelensky also offered to provide “the necessary assistance” to Turkey, whose combat drones are helping Kyiv fight the Russian invasion.
Images on Turkish television showed rescuers digging through rubble across city centres and residential neighbourhoods of almost all the big cities running along the border with Syria.
Some of the heaviest devastation occurred near the quake’s epicentre between Kahramanmaras and Gaziantep, where entire city blocks lay in ruins under the gathering snow.
Kahramanmaras Governor Omer Faruk Coskun said it was too early to estimate the death toll because so many buildings were destroyed.
“It is not possible to give the number of dead and injured at the moment because so many buildings have been destroyed,” Coskun said. “The damage is serious.”
A famous mosque dating back to the 13th century partially collapsed in the province of Maltaya, where a 14-story building with 28 apartments also collapsed.
In other cities, anguished rescuers struggled to reach survivors trapped under the debris.
“We hear voices here — and over there, too,” one rescuer was overheard as saying on NTV television in front of a flattened building in the city of Diyarbakir.
“There may be 200 people under the rubble.”
The Syrian health ministry reported damage across the provinces of Aleppo, Latakia, Hama and Tartus, where Russia is leasing a naval facility.
AFP correspondents in northern Syria said terrified residents ran out of their homes after the ground shook.
Even before the tragedy, buildings in Aleppo, Syria’s pre-war commercial hub, often collapsed due to the dilapidated infrastructure, which has suffered from lack of war-time oversight.
Naci Gorur, an earthquake expert with Turkey’s Academy of Sciences, urged local officials to immediately check the region’s dams for cracks to avert potentially catastrophic flooding.
Officials cut off natural gas supplies across the region as a precaution.
Turkey is in one of the world’s most active earthquake zones.
The Turkish region of Duzce suffered a 7.4-magnitude earthquake in 1999 — the worst to hit Turkey in decades.
That quake killed more than 17,000 people, including about 1,000 in Istanbul.
Experts have long warned a large quake could devastate Istanbul, which has allowed widespread building without safety precautions.
A magnitude-6.8 quake hit Elazig in January 2020, killing more than 40 people.
And in October that year, a magnitude-7.0 quake hit Turkey’s Aegean coast, killing 114 people and wounding more than 1,000.
The last 7.8-magnitude tremor shook Turkey in 1939, when 33,000 died in the eastern province of Erzincan.
