When a shooting happened at the STEM School Highlands Ranch in Colorado on the 7th May, 11-year-old Sasha hid in a gym closet with some of his classmates, they all escaped.

One student in the school was killed and seven others were injured, just 8km from Columbine High - the site of one of America's most notorious school shootings 20 years ago.

Sasha explains how even at 11, he had a plan of what to do when a shooting happened.
