London’s Metropolitan Police said they had been alerted to an apparent fight outside the Iranian embassy on Friday, which local media reported occurred during a protest against the Iranian leadership.

Police said eight people were arrested in connection with the incident, including one man who was in hospital with serious but non-life threatening injuries. Another man was also hospitalised.

“Seven of those arrested were charged with causing grievous bodily harm,” police said in a statement. “All are Iranian nationals.”

Police said that they had been remanded in custody ahead of a court appearance on Monday. The eighth person was still in hospital and had been bailed, they added.
