Police Fire Shots After Ukraine Ambassador's Car 'Rammed' in London

Police in London opened fire outside the Ukrainian embassy after a man rammed his vehicle into the ambassador's empty parked car at least twice before being arrested.

No one was hurt in the incident, which happened early on Saturday (local time) outside the embassy building in the affluent Holland Park area of west London, and it was not being treated as terrorism, police said in a statement.

The embassy said in a statement that the ambassador's empty official vehicle had been deliberately rammed as it sat parked in front of the building.

"The police were called immediately, and the suspect's vehicle was blocked up," it added.

"Nevertheless, despite the police actions, the attacker hit the ambassador's car again. In response, the police were forced to open fire on the perpetrator's vehicle."

TV footage later showed a silver car slewed across the cordoned-off road with its driver's door open and window shattered.

Police said they had been called at around 9.50am on Saturday to reports of a car having hit several vehicles in the road.

"On arrival at the scene, a vehicle was driven at police officers," they added in a statement.

"Police firearms and Taser were discharged, the vehicle was stopped and a man, aged in his 40s, was arrested."
