One officer was seen lying stricken next to a patrol vehicle

Five police officers have been shot dead and six others wounded during a protest against the deaths of two black men shot by police - as tensions rise across America. The officers were shot dead at a Black Lives Matter protest in Dallas, Texas, as two snipers are believed to have targeted the officers from an 'elevated position' in a multi-story car park.
The protest massacre comes in the wake of the deaths of two black men shot dead by police within hours of each other.
