Twelve arrests at al-Quds Day rally and counterprotest in London

Metropolitan police say they are also investigating chants led by Bobby Vylan at pro-Palestine protest next to Thames

Twelve people were arrested as hundreds joined a pro-Palestinian al-Quds Day demonstration on one side of the Thames, while hundreds more gathered on the opposite bank to back Israeli and American attacks on Iran.

Al-Quds Day is an international demonstration of support for Palestinian rights. The event takes its name from the Arabic for Jerusalem and was established by Ayatollah Ruhollah Khomeini after Iran's 1979 revolution.
