The London Metropolitan Police used batons to disperse peaceful protestors and arrested dozens of demonstrators calling on the UK government to reverse its decision to designate Palestine Action as a terrorist group.

Hundreds had gathered in Westminster’s Parliament Square on Saturday, holding cardboard placards reading “I support Palestine Action” and flags in support of Palestine.

One protestor was seen with blood streaming down his face after they were arrested at the rally. While another protestor could be heard screaming that the police had hurt his back during their arrest.

Among the group of people detained by the police included scores of elderly protestors and families of Holocaust survivors who sat silently on the green in Parliament Square.
