Belgian riot police have fired tear gas and water cannon during clashes with demonstrators while an estimated 100,000 people marched through Brussels in the first mass protests against the new government’s austerity measures.
Demonstrators overturned cars and threw paving stones and fireworks during Thursday’s protest, which opposes economic reforms announced by Prime Minister Charles Michel’s centre-right coalition.
Riot police armed with clubs and shields charged the rowdiest groups of demonstrators, who also set rubbish bins on fire and made makeshift barricades.
Paramedics treated at least one protester, who suffered a broken nose.
The rally, which started peacefully but turned violent, is the first in a series of measures planned by Belgian trade unions including strikes in several provinces in coming weeks, followed by a general strike throughout the kingdom on December 15.
Police said there were at least 100,000 demonstrators in Brussels while the unions said up to 130,000 protesters showed up.
Rail companies had sold low-cost tickets to increase protest numbers in the capital.
Public transport services were restricted because of the protests, partially paralysing the capital of the European Union on a day that finance ministers from countries that use the euro were gathering there.
