UK head of Greenpeace arrested for stunt protesting US arms sales to Israel

British police arrest the UK head of Greenpeace, alongside five other activists, after they poured 300 liters of blood-red dye into a pond at the US embassy today in protest against the US sale of arms to Israel.

Will McCallum, the environmental campaign group’s UK head, and the others, disguised as delivery riders on bicycles with trailers, Greenpeace says, tipped the dye into the high-security embassy’s semicircular pond.

McCallum and the others were arrested on suspicion of conspiracy to cause criminal damage, which carries a maximum sentence of 10 years in prison. The Met Police did not immediately respond to a request for comment.

Areeba Hamid, co-executive director at Greenpeace, says the group “took this action because US weapons continue to fuel an indiscriminate war that’s seen bombs dropped on schools and hospitals, entire neighbourhoods blasted to rubble, and tens of thousands of Palestinian lives obliterated.”
