Protests against the shootings of two black men by police officers shut down main arteries in a number of U.S. cities on Saturday, leading to numerous arrests, scuffles and injuries in confrontations between police and demonstrators.
Undeterred by heightened concerns about safety at protests after a lone gunman killed five police officers in Dallas Thursday night, organizers went ahead with marches in the biggest metropolis, New York City, and Washington D.C., the nation’s capital, among other cities.
Dallas police headquarters and surrounding blocks were cordoned off and SWAT teams were deployed on Saturday after authorities received an anonymous threat against officers across the city, but a search for a “suspicious person” turned up no one, officials said.
The incident occurred as the city remained tense following Thursday night’s fatal shootings of five Dallas police officers by a former U.S. Army reservist. Police asked news organizations to stop airing live video from the area as they carried out the search.
