The 'March For Our Lives' (MFOL) protest was organised by survivors of the Valentine's Day shooting at Marjory Stoneman Douglas High School in Parkland, Florida.
17 people were killed when a former student opened fire at Stoneman Douglas High School in Parkland, just north of Miami.

In the weeks since the attack, the MFOL movement has gained a number of celebrity supporters, raised money and even persuaded various businesses to cut ties to the National Rifle Association (NRA).
The biggest gathering is due to take place in Washington DC later today.
