Aug. 9 (UPI) -- More than 200 people were arrested in London Saturday during a major pro-Palestinian protest in the British capital, police confirmed.

"We've now arrested 150 people in Parliament Square. While many of those remaining in the Square are media and onlookers, there are still people holding placards supporting Palestine Action," the Metropolitan Police Service said in an update on X.

"Officers are steadily working through the crowd making further arrests," added ahead of an update that confirmed the more-accurate arrest count.

"We're aware of a statement by Defend Our Juries (the organizers of today's protest) claiming we were only to arrest 'a fraction' of those breaking the law in Parliament Square this afternoon," the Met said on X.

"That claim simply isn't true. We estimate there were 500 to 600 people in Parliament Square when the protests began, but many were onlookers, media, or people not holding placards in support of Palestinian Action.
