The dissident Chinese artist Ai Weiwei says the authorities in Beijing have demolished his studio there.
In a series of clips on Instagram showing the former factory being torn down, Ai said that he had been given no notice of the decision.
Another of his studios in Shanghai was destroyed in 2011. He also said at that time he had received no warning.
The 66-year-old has lived in Germany since leaving China in 2015. He is a strong critic of China’s government.
On Instagram Ai said “farewell” to the space, which he had used since 2006.
