Spain’s prime minister, Pedro Sánchez, has called for an end to “the violent and irrational behaviour” of a minority of people after a weekend of angry demonstrations in cities around the country against the government’s decision to declare a six-month state of emergency in response to the coronavirus pandemic.

Thirty-two people were arrested and 12 injured in Madrid on Saturday night after a protest over the region’s midnight to 6am curfew turned violent, with rubbish bins set alight on the city’s Gran Vía and skirmishes with police.

There were also protests over the weekend in Barcelona, Málaga, Vitoria, Valencia, Santander and Burgos.

Police in Logroño, the capital of the La Rioja region, arrested six people on Saturday night after bins were torched and some shops smashed and looted. Videos showed shop windows being broken and large crowds of people running from riot police.
