US must take 'serious action' after Floyd's killing: UN

The UN rights chief voiced alarm Thursday at the death in police custody of George Floyd, demanding that US authorities take "serious action" to put a stop to killings of unarmed African Americans.

"This is the latest in a long line of killings of unarmed African Americans by US police officers and members of the public," Michelle Bachelet said in a statement, insisting that "US authorities must take serious action to stop such killings, and to ensure justice is done when they do occur."
