Protesters in several Spanish cities have clashed with security forces for a second night running, police said, as exasperation and anger over coronavirus restrictions grow worldwide, reported AFP.

Anger spilled onto the streets in sometimes violent fashion overnight on Saturday, with looting and vandalism breaking out in some cities on the fringe of protests.

The biggest disturbances were in Madrid where scores of demonstrators chanting “freedom!” torched rubbish bins and set up makeshift barricades on the city's main thoroughfare, the Gran Via, images on social media showed.

When police moved in to clear the gathering, they were pelted with stones and flares.

The country has imposed a nationwide nighttime curfew and almost all of Spain's regions have imposed regional border closures to prevent long-distance travel.
