The number of arrests at Saturday's demonstration in London in support of banned group Palestine Action has risen to 532. The Metropolitan Police said the majority of arrests - 521 - were for displaying placards in support of Palestine Action at Westminster's Parliament Square, and one at a Palestine Coalition march.

The government has said supporters of a "terrorist organisation will feel the full force of the law" after a protest in support of the proscribed group Palestine Action led to more than 500 arrests on Saturday.

Police in London have detained more than 466 people who were protesting the United Kingdom’s decision to ban the Palestine Action Group, marking the “largest ever mass arrest” at a single protest in the British capital, according to campaigners.
