Thousands of rescue workers combed through flattened villages in southwest China on Sunday in a race to find survivors from a powerful quake as the toll of dead and missing rose past 200.
Dressed in bright orange uniforms, rescuers battled their way up mountain paths strewn with wreckage to reach isolated parts of Sichuan province on the edge of the Tibetan Plateau.
Troops had worked through the night, searching villages where houses had been destroyed for survivors and treating those injured in the quake.
The death toll rose to at least 186, the official Xinhua news agency said, but reports of casualties slowed Sunday.
More than 11,300 people were injured and 21 remain missing, Xinhua said, citing local officials, adding that 1.5 million had been affected.
China’s new Premier Li Keqiang rushed to the disaster zone to oversee rescue efforts in his first major public test since taking office in March, before returning to Beijing late Sunday, China Radio National reported.
Li said on Saturday that the first 24 hours was “the golden time for saving lives”, as China’s new leaders respond to a fresh disaster five years after another Sichuan earthquake left more than 90,000 people dead or missing.
The rescue operation was hampered by huge queues of traffic — some stretching back for 20 kilometres (12 miles) — clogging roads into the disaster zone.
“We really want to go in and help people, but instead we are waiting in traffic,” one frustrated relief official said in his car, as large numbers of volunteers tried to head to the zone.
Boulders the size of cars littered streets in Lushan county, the epicentre of the earthquake.
“Three people died in that building, and no one wants to live in this area any more because it is too dangerous,” a 45-year man surnamed Yang told AFP, surrounded by rubble from the quake.
At least 1,700 aftershocks have followed since the quake struck Saturday morning, Xinhua reported late Sunday. Chinese seismologists registered the tremor at 7.0 magnitude while the US Geological Survey gave it as 6.6.
Firefighters helped by sniffer dogs have pulled 91 people alive from the rubble, Xinhua said, citing the Ministry of Public Security.
At Lushan People’s Hospital, a steady stream of ambulances continued to arrive in the early hours of Sunday. Most victims were taken to tents erected in the grounds of the hospital, where doctors treated the injured.
A 68-year-old woman with a broken arm spoke of the terror she experienced when the earthquake struck.
“It was as if the mountain was alive,” she told AFP. “Now I have no home to go. So I don’t know what I am going to do.”
President Xi Jinping ordered all-out efforts to minimise casualties, Xinhua said.
Quake-prone Japan, which has been mired in tensions with China over a high-seas territorial dispute, offered any help that is required.
“Japan is ready to offer its maximum support,” Prime Minister Shinzo Abe said in a message to Xi and Li, according to Japan’s foreign ministry.
In Rome, Pope Francis said his “thoughts go to the numerous people” affected by the disaster.
