SWEDISH CLIMATE ACTIVIST Greta Thunberg has been arrested at a protest in London in support of Palestine Action protesters who are on hunger strike in prison.

It comes after the 22-year-old visited President Catherine Connolly at Áras an Uachtaráin on a courtesy call last week before taking part in a public fundraising event at Bohemian FC’s Dalymount Stadium in support of humanitarian aid for families in Gaza.

In a video shared by the Prisoners for Palestine protest group, Thunberg can be seen holding a sign reading ‘I support the Palestine Action prisoners. I oppose genocide’ at a demonstration outside the central London offices of Aspen Insurance.

The protest group claimed they targeted the company this morning because they provide services to Israeli-linked defence firm Elbit Systems.

Two other activists sprayed red paint over the front of the building before police arrived and made arrests.

A City of London Police spokesperson said: “At around 7am this morning hammers and red paint were used to damage a building on Fenchurch Street.

“A man and a woman have been arrested on suspicion of criminal damage. They glued themselves nearby and specialist officers are working to release them, and bring them into police custody.

“A little while later, a 22-year-old woman also attended the scene. She has been arrested for displaying an item (in this case a placard) in support of a proscribed organisation (in this case Palestine Action) contrary to Section 13 of the Terrorism Act 2000.”

Palestine Action has been classified as a terrorist organisation by the UK government, but some members of parliament have voiced their support for the detained activists and protests have been held outside the prison in Surrey where they are being held.

Thunberg has spoken out previously about the hunger strikers, who are in prison awaiting trial for alleged break-ins or criminal damage on behalf of Palestine Action before the group was banned.

She described the activists as “political prisoners” in a video posted on her Instagram on Monday, adding the UK government should meet their demands to be released from custody and for charges to be dropped.

The imprisoned Palestine Action activists began their hunger strike on 2 November, the anniversary of the Balfour Declaration of 1917, a public pronouncement of the British government’s support for the establishment of a Jewish state in Palestine.

A total of seven activists – including one who has refused to eat for 52 days – have been taken to hospital in recent days.

Kamran Ahmed (28), who was being held at Pentonville Prison in London, and Amu Gib, (30), who was being held at HMP Bronzefield in Surrey, have both been admitted to hospital in the last week after refusing food.

Prisoners for Palestine previously said Gib’s health has “deteriorated rapidly” since joining the hunger strike on 2 November, and the activist now needs to use a wheelchair.

Gib was taken to hospital on Saturday.

A legal firm representing the hunger strikers has said it submitted a pre-action letter on Monday against the Justice Secretary David Lammy.

The letter outlines the group’s intention to initiate legal action.
