The thieves arrived between 7.30am and 7.40am and stole jewellery, a source following the case said, adding its value was still being estimated.

A separate police source said the robbers had drawn up on a scooter armed with small chainsaws and used a goods lift to reach the room they were targeting.

France’s culture minister Rachida Dati earlier today reported a break-in at the Louvre in Paris.

“A robbery took place this morning at the opening of the Louvre Museum,” she wrote on X.

“No injuries reported. I’m on site with museum staff and police,” she added.

The Louvre said on X it was closing its doors for the day “for exceptional reasons”.

However, contacted by AFP, it did not wish to immediately provide further comment.

The seat of French kings until Louis XIV abandoned it for Versailles in the late 1600s, the Louvre is regularly listed as the world’s most visited museum.
