Zelensky was not seriously injured but the driver of the other vehicle was taken away by ambulance Russian missiles attack dam in attempt to flood another city, Ukraine says Russian, Chinese navies conduct joint patrols in the Pacific
"Doctors who accompany the president checked him, no serious injuries were detected," Serhiy Nykyforov, a spokesman for Zelensky said in a post on Facebook.
A passenger car collided with a vehicle carrying the president as his motorcade that was returning to Kyiv from the Kharkiv region, Nykyforov wrote, without indicating what sort of injuries the president may have received. He added the collision is under investigation.
The driver of the other vehicle was taken away by ambulance.
"Doctors accompanying the head of the state provided emergency aid to the driver of the car and transferred him to ambulance," Nykyforov wrote.
Zelensky was returning from Izium, the biggest city recaptured last week during a counteroffensive in the country's northeast. The development was his country's most significant battlefield victory in months.
It came as Russian troops targeted critical infrastructure in the president’s home town.
Eight cruise missiles hit water equipment hit Kryvyi Rih, a city on the Inhulets River 93 miles south-west of Dnipro, according to the deputy head of the president’s office, Kyrylo Tymoshenko, on his Telegram channel.
Mr Zelensky said the strikes appeared to be an attempt to flood the city and that a dam on a reservoir was hit.
Zelensky said towns and villages recaptured from Russian forces had been devastated, while a major city struggled to contain damage to its water system from missile attacks by Kremlin's forces.
Kryvyi Rih, the largest city in central Ukraine with an estimated pre-war population of 650,000, was targeted by eight cruise missiles on Wednesday, officials said.
"The water pumping station was destroyed. The river broke through the dam and overflowed its banks. Residential buildings are just a few metres away from the river," Ukrainian legislator Inna Sovsun said on Twitter.
The missile strikes hit the Karachunov reservoir dam, Zelenskiy said in a video address released early on Thursday. The water system had "no military value" and hundreds of thousands of civilians depend on it daily, he said.
Russian forces suffered a stunning reversal this month after Ukrainian troops made a rapid armoured thrust in the Kharkiv region, forcing a rushed Russian withdrawal.
Zelensky on Wednesday made a surprise visit to Izium - until four days ago Russia's main bastion and logistics hub in the region - where he watched as the blue and yellow Ukrainian flag was raised in front of the charred city council building.
"Our law enforcers are already receiving evidence of murder, torture, and abductions of people by the occupiers," Zelensky said in his address.
"They only destroyed, only seized, only deported. They left devastated villages, and in some of them there is not a single surviving house," he added.
Russia denies deliberately targeting civilians.
Russian President Vladimir Putin and his Chinese counterpart Xi Jinping are set to discuss Ukraine and Taiwan at a meeting in Uzbekistan on Thursday which the Kremlin said would hold "special significance".
Ahead of the meeting, the navies of the two countries conducted joint tactical manoeuvres and exercises involving artillery and helicopters in the Pacific Ocean.
Moscow and Beijing declared a "no limits" partnership earlier this year, backing each other over standoffs on Ukraine and Taiwan with a promise to collaborate more against the West.
Also on the diplomatic front, the U.N. General Assembly is on Friday due to consider a proposal for Zelensky to address the annual gathering of leaders next week with a pre-recorded video. Russia is opposed to Zelensky speaking.
Away from Ukraine, Russian authorities are facing challenges in other former Soviet states, with deadly fighting between Azerbaijan and Armenia and border guard clashes between Kyrgyzstan and Tajikistan.
Western politicians and military officials have said it was too early to tell whether Ukraine's recent success marked a turning point because Russia had yet to fully respond.
"We should avoid euphoria. There is still a lot of work to be done to liberate our lands, and Russia has a large number of weapons," Oleksiy Danilov, secretary of the national security and defence council, said in an online post.
Ukraine Foreign Minister Dmytro Kuleba, in a Twitter post after the attacks on Kryvyi Rih, said "Russia is a terrorist state and must be recognised as such".
In that vein, U.S. senators from Democratic and Republican parties introduced legislation that would designate Russia as a state sponsor of terrorism. The measure is opposed by President Joe Biden's administration.
Back in Izium, smashed windows, pock-marked facades and scorched walls lined a battle-scarred main thoroughfare comprised of deserted meat shops and pharmacies and ruined beauty salons. A forlorn handwritten sign on a door read: 'People live here'.
With a pink hood wrapped around her face for warmth, Liubov Sinna, 74, said Izium residents were still fearful.
"Because we lived through this whole six months. We sat it out in cellars. We went through everything it is possible to go through. We absolutely cannot say that we feel safe," she said.
She said the town stood at the "gates of the Donbas", the eastern region whose entire capture Putin has talked up as a key war objective.
German Chancellor Olaf Scholz, who spoke to Putin over the phone this week, said the Russian president "unfortunately" still did not think his invasion was a mistake.
Putin says he wants to ensure Russian security and protect Russian-speakers in Ukraine. Ukraine and the West accuse Russia of an unprovoked war of aggression.
In a move that suggests Putin had wider war aims when he ordered troops into Ukraine on February 24, three people close to the Russian leadership told journalists that Putin had rejected a provisional deal with Kyiv around the time the war began.
They said the deal would have satisfied Russia's demand that Ukraine stay out of the U.S.-led Western military alliance NATO. The Kremlin said the Reuters report had "absolutely no relation to reality". It also said Ukraine's ambitions to join NATO still presented a threat to Russia.
