The revolver with which Vincent van Gogh is believed to have shot himself is to go under the hammer Wednesday at a Paris auction house.

Billed as "the most famous weapon in the history of art", the seven mm Lefaucheux revolver is expected to fetch up to 60,000 euros ($67,000).

Van Gogh experts believe that he shot himself with the revolver near the village of Auvers-sur-Oise north of Paris, where he spent the last few months of his life in 1890.

Discovered by a farmer in 1965 in the same field where the troubled Dutch painter is thought to have fatally wounded himself, the gun has already been exhibited at the Van Gogh Museum in Amsterdam.

China's powerful President Xi Jinping has been dealt a rare setback with the suspension of unpopular legislation in Hong Kong following massive protests, but Beijing could bite back by tightening its grip on the semi-autonomous city, according to analysts.

Hundreds of thousands of protesters returned to the streets of Hong Kong on Sunday, calling for the resignation of the territory's pro-Beijing leader Carrie Lam -- even after she suspended a deeply unpopular bill that would have allowed extraditions to the mainland.

Xi is not used to such challenges, having consolidated his power and tightened his grip on civil society on the mainland since taking office in 2012.
