Thousands of students rallied on London's Parliament Square on Friday, as part of nation-wide protests demanding the government take more action to fight climate change.

"We're not gonna back down, we're not gonna be quiet about climate change and the environment, because it's so important," said Kayleigh, a protester.

Organisers said it was the first nation-wide youth strike for climate, following similar protests gripping Belgium and other countries.

Downing Street said that while it was important for young people to engage with issues like climate change, the disruption to planned lesson time was damaging for pupils.
