Devastation as thousands die in huge earthquakes
● Death toll across Turkey and Syria put at 3,000 and rising with hundreds still trapped ● Rescuers search wreckage as president declares seven days of national mourning
More than 3,000 people have died after two powerful earthquakes toppled hundreds of buildings across wide swathes of Turkey and Syria.
Hundreds of people are still believed to be trapped under rubble, and the death toll is expected to rise as rescue workers search mounds of wreckage in cities and towns across the area.
Turkish President Recep Tayyip Erdogan declared seven days of national mourning.
Authorities feared the death toll would keep climbing as rescuers searched through tangles of metal and concrete for survivors in a region beset by more than a decade of Syria's civil war and a refugee crisis.
On both sides of the border, residents, jolted out of sleep by the first, pre-dawn quake, rushed outside on a cold winter's night.
Nearly 1,500 people were killed in 10 Turkish provinces, with some 8,500 injured, according to the president of the country's disaster management agency.
The death toll in government-held areas of Syria climbed past 430 people, with some 1,280 injured, according to the health ministry.
In the country's rebel-held northwest, groups that operate there said the death toll was at least 380, with many hundreds more injured.
Buildings were reduced to piles of pancaked floors, and major aftershocks or new quakes, including one nearly as strong as the first, continued to rattle the region.
Rescue workers and residents in multiple cities searched for survivors, working through tangles of metal and concrete.
A hospital in Turkey also collapsed, and patients, including newborn babies, were evacuated from facilities in Syria.
Mr Erdogan said: "Because the debris removal efforts are continuing in many buildings in the earthquake zone, we do not know how high the number of dead and injured will rise.
"Hopefully, we will leave these disastrous days behind us in unity and solidarity as a country and a nation."
The first earthquake, which was centred on Turkey's south-eastern province of Kahramanmaras, was felt as far away as Cairo. It sent residents of Damascus rushing into the street, and jolted awake people in their beds in Beirut. In the Turkish city of Adana, one resident said three buildings near his home were
toppled. The tremor struck a region that has been shaped on both sides of the border by more than a decade of civil war in Syria.
On the Syrian side, the region affected is divided between government-held territory and the country's last opposition-held enclave, which is surrounded by Russian-backed government forces. Turkey, meanwhile, is home to millions of refugees from that conflict.
The opposition-held regions in Syria are packed with some four million people displaced from other parts of the country by the fighting. Many of them live in buildings that are already wrecked from past bombardments. Hundreds of families remained trapped in rubble, according to the opposition emergency organisation, the White Helmets.
Strained health facilities and hospitals were quickly filled with injured, rescue workers said. Others had to be emptied, including a maternity hospital, according to the SAMS medical organisation.
The regions its on top of major fault lines and is frequently shaken by earthquakes. Some 18,000 people were killed in a similarly powerful earthquakes that hit north-west turkey in 1999.
The US Geological Survey measured yesterday's quake at 7.8. Hours later, a 7.5 magnitude one struck more than 60 miles away. An official from Turkey's disaster management agency said it was a new earthquake, not an aftershock.
Hundreds of after shocks were expected after the two tremors, the official told reporters.
Thousands of buildings were reported collapsed in a wide area extending from Syria' s cities of Aleppo and Hamatodiya rb akir, more than 200 miles to the north-east.
A hospital collapsed in the Mediterranean coastal city of Is ken de run, but casualties were not immediately known, Turkish vice president Fuat Oktay said.
Televisions stations in Turkey aired screens split into four or five, showing live coverage from rescue efforts in the worst-hit provinces. In the city of K ah ram an mar as, rescuers pulled two children alive from the rubble, and one could be seen lying on a stretcher on the snowy ground.
Offers of help – from searchand-rescue teams to medical supplies and money – poured in from dozens of countries, as well as the european union and Nato.
In Turkey, people trying to leave-the-quake-stricken-regions caused traffic jams, hampering efforts of emergency teams trying to reach the affected areas.
Authorities urged residents not to take to the roads. Mosques around the region were opened to provide shelter for people unable to return to damaged homes amid temperatures that hovered around freezing.
In Diyarbakir, hundreds of rescue workers and civilians formed lines across a mountain of wreckage, passing down broken concrete pieces, household belongings and other debris as they searched for trapped survivors while diggers sifted through the rubble below.
The quake damaged a historic castle perched on top of a hill in the centre of the provincial capital of Gaziantep, about 20 miles from the epicentre. Parts of the fortresses' walls andwatch towers were level led and other parts heavily damaged, images from the city showed.
Meanwhile, the directorate general of Antiquities and Museums in Syria said the earthquake had caused some damage to the Crusader-built Marqab, or watch tower castle, on a hill overlooking the Mediterranean. Parts of a tower and some walls collapsed.
In the small Syrian rebel-held town of Azmarin in the mountains by the Turkish border, the bodies of several dead children, wrapped in blankets, were seen being brought to a hospital.
In north-west Syria, the quake added new woes to the opposition-held enclave centred on the province of Idlib, which has been under siege for years, with frequent Russian and government air strikes. The territory depends on a flow of aid from nearby Turkey for everything from food to medical supplies.
The opposition's Syrian Civil Defence described the situation there as "disastrous".
Rescue workers and civilians passed chunks of concrete to each other across mountains of rubble in a desperate search for survivors trapped by a devastating earthquake.
In some places around Turkey, survivors could be heard screaming from beneath collapsed buildings.
In Kahramanmaras province in Turkey, rescuers pulled two children alive from the rubble.
In Adana, Turkey, about 20 people, some in emergency rescue jackets, used power saws to carve out space that would let any survivors climb out or be rescued. Later, mechanical diggers joined the efforts as bright spotlights illuminated the wreckage.
Residents lifted rubble and unearthed people heard screaming from beneath buildings.
Turkish military ambulance planes were transporting the injured to Istanbul and Ankara hospitals, the defence ministry said.
Rescuers from across Turkey tried to make it to the provinces amid heavy snow and rainstorms.
In Syria, a man held the body of a girl in his arms beside a two story collapsed building as he walked away from the debris.
He and a woman set the girl on the ground, wrapping her in a large blanket to protect her from the rain.
An official with turkey' s disastermanagement authority said 6,445 people had been rescued across 10 provinces.
The official, Orhan Tatar, said 5,606 buildings had collapsed.
