British police are investigating chants of 'Death to the Israeli military' made during a pro-Iran Al-Quds rally in central London, where thousands gathered after authorities banned a planned march due to concerns over serious disorder. The chant was led by musician Bobby Vylan as part of the annual demonstration held on the south bank of the River Thames.

The event was organized by the Islamic Human Rights Commission, which described it as a peaceful show of support for Palestinians. Critics, including several Members of Parliament and peers, labeled it a hate rally and alleged links between the organizers and the Iranian government. Police kept rally participants and counter-protesters separated using the river as a buffer zone to prevent clashes.

Twelve people were arrested for offenses including support for a banned organization and threatening behavior. Authorities confirmed they are also examining remarks made by Vylan during the rally, noting concern about the impact of the chants on London’s Jewish communities. Al-Quds Day, established in 1979 by Iran’s revolutionary leadership, is marked annually in cities worldwide with demonstrations against Israel.
