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.
"We intend to provide any assistance that we can to investigate this attack," Lynch stated during a press conference.
"To all Americans, I ask you, I implore you, do not let this week precipitate a new normal in this country," Lynch stated.
She called for a "calm and peaceful" response to racially profiled incidents.
Earlier in the day, Dallas Police Chief David Brown said the suspect in the deadly police attack been killed by a bomb planted by the law enforcement after negotiations had broken down.
