The arrest came after the British government said it would ban Palestinian actions under anti-terrorism laws.
British police arrested four people last week in connection with the Palestinian protest. There, a military plane was destroyed at an airbase in the UK, in an action claimed by the Palestinian Action Group.
On June 20, two activists from the Palestinian action broke into the Royal Air Base in Brize Norton, Oxfordshire, damaging and spraying red paint on two planes used for fueling and transport.
29 women, ages 29 and 24, and two men, were arrested on Friday on suspicion of preparing or incitement for a “terrorist” act, while 41 other women were arrested on suspicion of supporting criminals, according to a counterterrorism statement police the Southeast (CTPSE).
The four arrests said they were made in London and Berkshire, southeastern England.
Palestinian actions denounced the government’s arrest, accusing Israeli war crimes of being “in the pockets of armed arms companies armed with armed war crimes.”
Authorities accused them of “crashing non-violent protests disrupting the flow of weapons to Israel during genocide in Palestine.”
The group posted a video online last Friday. Showing people inside the base, it appeared to be on an electric scooter on an Airbus Voyager inter-air refueling tanker before one person sprayed paint on the jet engine.
British Prime Minister Kiel Starmer has condemned the law as “disgrace.”
Interior Secretary Yvette Cooper has decided to ban Palestinian actions after the incident and arrests will arrive a week before the ban comes into effect. If Congress approves the ban, support for the group would be a criminal offence punishable in prison for up to 14 years.
Cooper said the method became “more aggressive”, with its members showing “willingness to use violence” and that “such cases do not represent just or peaceful protest.”
“To prohibit Palestinian actions is a political gesture that will satisfy the pro-Israel groups and arms companies that are lobbying us to ban us as we are profitable and have a real impact on Israeli war machines.”
The government also said last week it was considering security at all British defense sites after the incident.
Palestine Action has staged other demonstrations, including spraying red paint on Allianz Insurance’s London office and destroying President Donald Trump’s Turnberry Golf Course in South Ayrshire, southern Scotland.
