Police in London are bracing for more demonstrations on Sunday as the war in Gaza continues to inflame tensions across the U.K. Demonstrators plan to march to the prime minister’s residence, demanding the release of hostages in Gaza. The march organizers emphasize the humanitarian aspect of their demand for the hostages’ release, saying it’s not a political issue. This follows the arrest of 474 people on Saturday at a protest supporting a banned pro-Palestinian group. The group, Palestine Action, was banned after activists damaged military planes. Supporters are challenging the ban in court.
