Ukrainians were being evacuated from President Volodmyr Zelensky's home city on Thursday after a Russian missile attack on a dam caused major flooding. 

The attack led to the River Inhulets bursting its banks while the dam and a pumping station were severely damaged. At least one bridge was destroyed and the streets were filled with flood water. 

It came as a spokesman for Mr Zelensky said he had escaped without injury after he was involved in a car accident in Kyiv on Thursday. 

The president was travelling in a motorcade through Kyiv on Wednesday when a motorist collided with his vehicle. 

"In Kyiv, a passenger car collided with the car of the President of Ukraine and escort vehicles," spokesman Sergiy Nikiforov said in a statement on Thursday morning.

"Medics accompanying the President provided the driver of the passenger car with emergency aid and transferred him to an ambulance," he continued.

"The president was examined by a doctor, no serious injuries were detected. The law enforcement officers will investigate all the circumstances of the accident."
