At least 19 children and two teachers are dead, after the worst school shooting in the United States since the Sandy Hook massacre.


Lone gunman Salvador Ramos, who was just 18, was also killed in the attack on primary-school aged children at Robb Elementary School in Texas.


It was the 27th school shooting in the US this year alone. Gun Violence Archive reports there have been 213 mass shootings in the United States this year, with 2,255 children aged 17 and under killed or injured by gun violence.

Today on Please Explain, North America correspondent Farrah Tomazin joins Bianca Hall to discuss the latest gun violence atrocity in the US.
