After a devastating earthquake in China's remote Tibet region killed at least 126 people and reduced houses and buildings to rubble, footage of motorists stopping on a shaking bridge was shared in social media posts falsely linking it to the powerful tremor.

More than 400 people trapped by a strong earthquake in the foothills of the Himalayas have been rescued, Chinese officials said, while over 30,000 residents have been relocated, as the search for survivors entered a second day on Wednesday.
