Rescuers struggled to reach a remote, rural corner of southwestern China on Sunday as the toll of the dead and missing from the country's worst earthquake in three years climbed to 203 with almost 1,000 serious injuries.

The 6.6 magnitude quake struck in Lushan county, near the city of Ya'an in the southwestern province of Sichuan, close to where a devastating 7.9 temblor hit in May 2008 killing some 70,000.

Most of the deaths were concentrated in Lushan, a short drive up the valley from Ya'an, but rescuers' progress was hampered by the narrowness of the road and landslides, as well as government controls restricting access to avoid traffic jams.

"The Lushan county centre is getting back to normal, but the need is still considerable in terms of shelter and materials," said Kevin Xia of the International Federation of Red Cross and Red Crescent Societies.

"Supplies have had difficulty getting into the region because of the traffic jams. Most of our supplies are still on the way," Xia said.

In Ya'an, relief workers from across China expressed frustration with gaining access to Lushan.

"We're in a hurry. There are people that need help and we have supplies in the back (of the car)," said one man from the Shandong Province Earthquake Emergency Response Team, who declined to give his name.

In Lushan, doctors and nurses tended to people in the open or under tents in the grounds of the main hospital, surrounded by shattered glass, plaster and concrete that fell during the quake. Water and electricity in the area were cut off by the quake.



"I was scared. I've never seen an earthquake this big before," said farmer Chen Tianxiong, 37, lying on a stretcher between tents, his family looking on.

Nearby, an elderly woman sat dazed mumbling to her son, while nurses wiped blood from another woman's foot as her husband cradled her head.

In another tent, Zhou Lin sat tending to his wife and three-day-old son who were evacuated from a Lushan hospital soon after the quake struck on Saturday.



"I was worried the child or his mother would be hurt. The buildings were all shaking. I was extremely scared. But now I don't feel afraid any more," said Zhou, looking at his child as he slept soundly wrapped in a blanket on a makeshift bed.

Premier Li Keqiang flew into the disaster zone by helicopter to comfort the injured and displaced, chatting to rescuers and clambering over rubble.

"Don't be sad, we will rebuild after this disaster and your new homes will be even better than before," state media quoted him as telling residents.



The Ministry of Civil Affairs put the number of dead at 179 and missing at 24, with almost 11,500 injured, 960 of them seriously.

Chen Yong, the vice director of the Ya'an city government earthquake response office, told reporters that the death toll was unlikely to rise dramatically.

"We understand the situation in most areas. Most of the casualties have been reported. In some remote mountain areas, it is possible that we don't fully understand the situation," he said.
