Hundreds of demonstrators were arrested in cities across the US this weekend, as protests against police shootings intensified and new details emerged about the motivations and plans of a man who killed five officers in Dallas.
During a weekend of protests over killings by police, more than 160 people were arrested in Baton Rouge, Louisiana, where demonstrations continued to grow over the fatal shooting by officers last week of Alton Sterling, a 37-year-old African American, as he was pinned down during a struggle.
Military-style vehicles, teargas and smoke grenades returned to American streets for the first time this summer, and Barack Obama appealed for calm and said those who attack law enforcement undermine the cause of social justice.
The unrest built as authorities in Dallas said Micah Johnson, who opened fire on officers late last Thursday, had been plotting a wider bombing campaign that could have had “devastating effects”. Johnson was said to have been seeking revenge for the police’s treatment of African Americans.
