An earthquake measuring 6.5 in magnitude has struck a remote and mountainous part of the southwestern province of Sichuan, killing seven people and trapping 100 tourists in a popular scenic spot.
The Sichuan earthquake administration said the epicentre of the tremor was in Ngawa prefecture, largely populated by ethnic Tibetans, many of whom are nomadic herders. It was also close to the Jiuzhaigou nature reserve, a tourist destination.
State television said seven people had been killed and 88 were injured, 21 of them seriously. The official People's Daily said five of the dead were tourists.
Sichuan's government added that 100 tourists had been trapped by a landslide, but that there were no reports of any deaths or injuries among them yet.
Sichuan government spokesman Chen Weide said it was unclear at present what had happened to them and whether they had been buried or were just trapped by a blocked road.
The Sichuan fire service said the reception area in a hotel had collapsed, trapping some people, but that 2800 people had already been safely evacuated from the building.
State television said another tourist had been pulled out alive from rubble in a different part of Jiuzhaigou.
While there was no confirmation of their nationalities, Jiuzhaigou is far more popular with Chinese tourists than foreigners, meaning the dead were likely to be Chinese.
The area is frequently struck by earthquakes.
Pictures on state media-run social media sites showed some damage in Jiuzhaigou, with tiles having fallen from buildings and people gathering outdoors.
State television said electricity had now largely been restored to the affected areas and the military was also sending rescuers to help with relief efforts. Jiuzhaigou airport was operating as normal after the runway was checked for damage, the report added.
A police official told state television that there had been some panic among the tourists when the quake hit.
The Sichuan government said on one of its official social media sites that more than 38,000 tourists were currently visiting Jiuzhaigou.
A quake in Sichuan in May 2008 killed almost 70,000 people.
