WASHINGTON (Sputnik) — Five Dallas police officers were shot and killed at a protest in the city that took place following the death of two black men who were killed by police in separate incidents in Louisiana and Minnesota. Police killed Johnson after the attack by exploding a bomb in the location where he was cornered.
"It is fitting that flags should be lowered to half-staff in memory of these dedicated and brave Texas law enforcement officers who were killed in the line of duty protecting others," Abbott stated.
US President Barack Obama said earlier in the day the deadly attack on police had been calculated, and pledged all those involved in the shooting would be held accountable.
Obama said the US Federal Bureau of Investigation (FBI) was in touch with the Dallas police over the attack.
