At least 184 people were arrested during Monday night's ongoing riots as at least 10 cops were injured as police in some cities fought back with water cannon and tear gas, officials said.

So far, rioters have struck in at least 20 cities and towns across the Netherlands since Saturday, when the nation was forced into its first curfew since World War II.

"We haven't seen so much violence in 40 years," Koen Simmers, of the police trade union NPB, said on television program "Nieuwsuur" ("Newshour").

Monday's violence left a trail of looted shops and burned cars in cities including Rotterdam, The Hague and the capital, Amsterdam, as well as a town close to it, Haarlem, according to Agence France-Presse (AFP).

Around 1,850 fines were handed out for breaking curfew along with the close to 200 arrests, officials told national broadcaster NOS.
