Climate change protestors have planned two separate protests in Cambridge city centre on Saturday.
They have been organised by Extinction Rebellion, who have gained notoriety for large-scale movements across the country.
This Saturday will see one protest take place near the Guildhall, called 'Blood of the Youth'.
The event's official Facebook page said: "On Saturday, XR Cambridge's Youth and Grandparents will join together to demonstrate that we all have blood on our hands and a responsibility to clean up our mess for future generations."
Later in the day, protestors will take to the River Cam in a movement called 'Red Rebels on the River - Water Scarcity Action'.
Extinction Rebellion say it's to highlight a recent drop in water levels.
The protest's Facebook page said: "Cambridgeshire is the driest part of Britain yet faces increasing water demand.
"In May 2019 the River Cam was at its lowest level of flow since records began in 1949. It may not look like it, but the river is drying up."
Extinction Rebellion have held several demonstrations in Cambridge, most recently in July when they blocked off a road outside the Grand Arcade shopping centre.
Cambridgeshire Police have told us they will be ready for this weekend's protests.
A statement from the force said: "We are aware of a planned protest due to be held in Cambridge on Saturday.
"A proportionate policing plan is in place, balancing the right to a peaceful protest while ensuring disruption to the wider community is kept to a minimum."
