The officers were taken to Erie County Medical Centre, where authorities said their condition was stable.

Police say four officers were hit by gunfire in St Louis, Missouri, after protests in the city which started peacefully on Monday became violent overnight, with demonstrators smashing windows and stealing items from businesses and fires burning in the central area.

Police chief Colonel John Hayden said two of the officers were shot in the leg, one in the foot, and the other in the arm.

"There is a reason we have been talking about social distancing for months. This could potentially be a so-called super spreading event."
Klaas Dijkhof, a member of parliament for the VVD party of Dutch prime minister Mark Rutte, said on Twitter he was "not only angry, but worried by the images out of Amsterdam". He called on demonstrators to voluntarily isolate themselves for two weeks.
