The death toll rose to 29 on Wednesday from a fire at a Beijing hospital, killing 26 patients and wounding dozens.
Social media showed dramatic videos of people using tied bed sheets to climb down the walls to escape smoke and flames after the fire broke out at Changfeng Hospital on Tuesday.
Broken and burnt windows could be seen at the site, where there were many police officers, some in plain clothes, Reuters witnesses said.
All but three of the 29 dead were patients, officials told a media briefing on Wednesday, with the fire having been put out in half an hour.
"There was a lot of smoke, I could see it," said an elderly local resident who gave only his surname, Li. He gave Reuters video clips he took of smoke billowing from the upper floors of the hospital.
Initial checks showed the fire, which mostly affected a wing for critically ill patients, was caused by inflammable painting material at a ward under renovation, the officials said.
By Wednesday, many social media posts critical about the fire on WeChat had been either censored or deleted, Reuters checks showed.
Early on Wednesday, 39 injured were still in hospital, three in critical condition, and 18 serious, the officials told the briefing.
