Eco-zealots threw paint over a 10 million GBP private jet while it was parked at the Ibiza Airport in Spain on Friday evening.

The activists from the extremist groups Futuro Vegetal and Extinction Rebellion claimed they were protesting over the lack of climate policies by Spanish political parties ahead of the general election on July 23.

They hurled yellow paint over the Embraer Phenom 300E while another demonstrator glued himself to the fuselage. Another protester unfurled a banner reading 'Your luxury=our climate crisis', in reference to the opulent plane made by the Brazilian firm.

Spanish Police said they arrested four activists involved in the attack on the aircraft, which costs around 13 million USD (10 million GBP) when bought new. They were held for nine hours before they were released Friday evening.

Airport operator Aena said the protest did not disrupt any flights in the Ibiza Airport.

The activists from Futuro Vegetal said they were protesting because, a week ahead of general elections, no Spanish political party was offering a package of measures to alleviate the climate crisis.

'It's the task of society, no matter who governs, to mitigate the effects of the climate crisis.

'The luxury industry consumes and contaminates common resources and all the life that inhabits the planet. The rich are a luxury we can't afford.'

Futuro Vegetal is becoming one of the highest-profile environmental groups in Spain, using dramatic displays of vandalism to draw attention to the climate crisis and animal welfare.

In June, the group took credit for covering a Mcdonald's in Murcia with paint to protest intensive farming.

Last November, two of the group's members glued themselves to frames of famous Goya paintings in the Prado Museum to call for action to meet the Paris climate targets.

This week, Spain has been suffering through a dramatic heatwave, with temperatures hitting above 40 C (104 F) in large parts of the country.

Globally, the beginning of July saw the hottest week on record, according to the World Meteorological Organization.
