Lynch called the attack "an unfathomable tragedy," and said the spate of violence can't be allowed to "precipitate a new normal."

The gunfire that killed five police officers and wounded seven others erupted during a protest march prompted by the shootings by police of black men in Louisiana and Minnesota.
