After scenes of joy in newly liberated Kherson the Ukrainian authorities have imposed a curfew and restricted travel in and out of the city, as the security situation remains tense.
There are fears that Russian troops, now digging in on the opposite bank of the Dnipro river, may resume shelling.
Kherson officials have banned use of river transport from 13 to 19 November.
Locals who fled have been warned not to return until their homes have been checked for mines or booby traps.
Russian explosives litter the region.
"The enemy mined all critical infrastructure objects," said Kherson governor Yaroslav Yanushevych.
The overnight curfew runs from 17:00 to 08:00 (15:00 to 06:00 GMT). Officials have returned to run Kherson's administration after the retreat of some 30,000 Russian occupation troops.
There are also fears that some Russian soldiers may have remained behind in disguise, while collaborators who helped the Russians during the occupation are now liable to be prosecuted.
In a reminder of the continuing threat, a volley of artillery fire hit the area of Kherson airport on Sunday.
President Volodymyr Zelensky said the Russians had destroyed all critical infrastructure in Kherson, depriving the city of heat, electricity, water and communications.
There was also widespread looting by the Russian army, Ukrainian officials say.
Raccoon meme
A video clip has surfaced showing a Russian soldier picking up a raccoon by its tail and throwing it into a cage inside an enclosure - reportedly in Kherson zoo.
The raccoon meme has gone viral on social media, with Ukrainians turning the raccoon - allegedly a prisoner of the Russians - into a war hero.
Ukrainians are joking about a message on Telegram by a Russian blogger, Anna Dolgareva, which said: "I was begged to provide some good news about Kherson, but really the only good news is that my comrade managed to steal a raccoon from Kherson zoo."
According to Oleksandr Todorchuk, founder of the animal welfare charity UAnimals, "the raccoon from Kherson zoo was stolen not just by some stupid soldier, but by the Russian command". In a Facebook post, he said: "They took most of the zoo's collection to Crimea: from llamas and wolves to donkeys and squirrels."
Kherson was the only regional capital to be captured by Russia since the February invasion of Ukraine.
The region, along with three others, was proclaimed by President Vladimir Putin to be part of Russia, at a ceremony in the Kremlin in September.
