Police have arrested six men after two pro-Israel protesters were attacked in a major incident outside the Iranian Embassy today.

Detectives have launched an urgent probe after the two men were set upon outside the embassy, which is opposite Hyde Park in west London, just before 10am.

Officers and paramedics swooped on Princes Gate, Knightsbridge, scrambling to detain suspects and treat the injured activists.

Witnesses told MailOnline how pro-Israeli protesters were chanting support for Israeli Prime Minister Benjamin Netanyahu and calling for the Iranian regime to be toppled before violence erupted and two of the activists were attacked.

It comes amid heightened tensions in the Middle East, with Iran and Israel locked in a brutal conflict that has escalated over the last week.
