The US Department of Justice has reportedly decided not to charge two white police officers who shot and killed a black man in Louisiana last summer.
Video footage appearing to show the officers holding down 37 year old Alton Sterling as they fired their weapons sparked days of protests in Baton Rouge.
Fifth anniversary of the Sandy Hook shooting massacre.
On December 14, 2012, twenty-year-old Adam Lanza used a Bushmaster rifle to fatally shoot 20 children and six adult staff members before turning the gun on himself at the Sandy Hook Elementary School in Newtown, Connecticut.
The incident was the fourth-deadliest mass shooting by a single person in modern U.S. history.
