Hundreds of school pupils have taken to the streets of Fort Lauderdale to call for stricter gun laws in the US days after a deadly shooting at a Florida high school.

Chants of "shame on you" rang out as survivors of the shooting at Marjorie Stoneman Douglas High School in Parkland stood alongside teachers and government representatives of several districts advocating gun control.

The anti-gun protest comes after a 19-year-old former student allegedly stormed the school on Wednesday and opened fire with a semi-automatic weapon, killing 17.

Since then, pupils have taken to social media, TV and the streets demanding a response from the authorities.

Some have particularly called out politicians who have taken campaign donations from the powerful National Rifle Association.
