More than one hundred arrests have been made during a week of protests at a major fuel terminal in Warwickshire.
On Wednesday evening the activist group Just Stop Oil claimed to be 'inside' the oil depot near Tamworth.
In a tweet, the group say they expect this to "impact on fuel supplies to petrol stations across England."
Warwickshire Police says a "significant operation" is underway in Kingsbury to deal with "protest activity."
On Thursday it confirmed that officers had made 15 arrests overnight, including for offences of criminal damage and going equipped.
In a statement, the force said it will always "respect people’s right to peaceful protest" but that it will "take action against those who break the law and significantly impact on the lives and livelihoods of others.”
That arrested remain in police custody and range in age from 25 to 71.
What are the protests about?
The climate activist groups Just Stop Oil and Extinction Rebellion have been protesting since Friday 1 April.
Demonstrators have been blocking key oil terminals around the country, including the Esso Birmingham Fuel Terminal in Birmingham and the Kingsbury Oil Terminal and the BP Oil Depot in Warwickshire.
The group says it's to raise awareness around the environmental costs of oil and gas.
They also say it's because "ordinary people can no longer afford oil and gas" and they believe the government should stop any expansion of the industry in the UK.
Chief Inspector Darren Webster from Warwickshire Police said: “Officers remain at the site of the protests and are taking action where we identify offences have been committed."
“I would like to reassure local people the protests today have been contained to the area around Trinity Road and there is only minimal disruption to the local community and local road network.”
The protestors have blocked access to a number of oil refineries across the UK over recent weeks, including in Kingsbury.
