Buckingham Palace in lockdown after 'sword attack'

A man with a "large knife" who assaulted two police officers outside Buckingham Palace has been arrested.
The officers suffered minor injuries and were taken to a hospital for treatment after the incident on Friday night.
The man, who is in his mid-twenties according to the police, was arrested on suspicion of grievous bodily harm and assault on police near Queen Elizabeth's London residence.
No members of the royal family were present in the palace at the time.
A Metropolitan Police spokeswoman was unable to comment on the motivation for the incident.
Britain has been hit this year by four militant attacks in which 36 people were killed, and the country's threat level is at severe, meaning an attack is highly likely.
A concert by pop star Ariana Grande in Manchester was attacked by a terrorist in May. Suicide bomber, Salman Ramadan Abedi, detonated a shrapnel-laden homemade bomb at the entrance to the concert, leaving 23 adults and children dead and 250 injured.

A witness near the scene said police had cordoned off a large area, including The Mall, a wide avenue leading up to the palace.

Footage on Sky News showed emergency vehicles lining the street



outside the palace.
"The man was stopped this evening... by officers at the Mall outside Buckingham Palace in possession of (a) knife," the police said in a statement.
"During the course of detaining him, two male police officers suffered minor injuries to their arm."
The suspect was taken to a London hospital for treatment of minor injuries, the police statement added.
There were no other reported injuries.
The police said the suspect will be questioned by detectives and that it is too early to speculate further.
One witness described seeing the man wrestled from a car by police having apparently driven his vehicle towards them.
Kiana Williamson told the Press Association: "We turned up and there was one police van and one car, there was also a civilian's car that had veered towards the police car.
"They were trying to get the man out of the car, shouting, more police were arriving on to the scene and the man was fighting back"
Ms Williamson said the encounter lasted about one minute.
The attack, the motivations of which are not know, comes only about an hour after another knife attack in a European capital, Belgium, where a man attacked two soldiers with a knife.
