Swedish activist Greta Thunberg joins teenagers calling for investment to fix teacher shortages and crumbling schools

More than 160,000 schoolchildren, students and trade unionists have marched in cities across France as protests over high school education continued into a third week and many demonstrators denounced policing tactics.

Riot police fired teargas at the end of Tuesday’s marches in Nantes and near the Montparnasse area of Paris, but most of the demonstrations over teacher shortages, overcrowded classes and crumbling school buildings held in cities including Lyon, Lille and Marseille were peaceful.

Thieves took four artworks but it is thought they dropped two in museum garden as they fled

French police are hunting two thieves who escaped with two Renoir paintings from a museum on the French Riviera after breaking in through a hole cut in its garden fence.

Bryan Masson, the mayor of Cagnes-sur-Mer, about 10 miles west of Nice, said the pair appeared to have been “well equipped and well informed” about the museum, which houses works by the French impressionist Pierre-Auguste Renoir in his former home.
