A man was arrested on Friday after attacking police with a knife outside Queen Elizabeth II’s Buckingham Palace residence in London, police said.
Two male police officers suffered minor injuries to their arm and the man was arrested on suspicion of grievous bodily harm and assault.
The officers were treated at the scene and did not require hospital treatment, according to police, who said it was too early to say whether the attack was terrorism.
No other injuries were reported.
A large number of police vehicles could be seen in the Mall, the wide road outside the palace.
Buckingham Palace is one of London’s main tourist attractions, and the London home of Queen Elizabeth II.
The queen, however, usually spends August in Scotland at her Balmoral estate with family members.
Enquiries are ongoing.
