Russia will introduce its ruble currency on the captured Ukraine region of Kherson from the start of May, state media has claimed.
Kherson was the first big city to be captured by Vladimir Putin ’s forces following the invasion started on February 24 and it remains in Russian hands despite local protests and counter-attacking from the Ukrainian military.
Now the deputy chairman of the region’s administration Kirill Stremousov has reportedly told the news agency RIA-Novosti that the ruble will be introduced during a transition taking four months.
During the in-between period both the ruble and the Ukrainian hryvnia will be used, he added.
In the news bulletin from RIA-Novosti it said that Russia is carrying out a “special operation to denazify and demilitarise Ukraine.”
At the same time, Russian forces used tear gas and stun grenades to disperse a pro-Ukraine rally in the occupied city of Kherson on Wednesday, Ukraine's Prosecutor General said.
Local authorities say Russia appointed its own mayor of Kherson on Tuesday after its troops took over the administration headquarters in the regional capital.
Some residents have staged occasional anti-occupation rallies and crowds gathered in the centre again on Wednesday, the date Kyiv had said Russia planned to stage a referendum to create a breakaway region like those in eastern Ukraine.
"During a peaceful pro-Ukrainian rally on Freedom Square in the city of Kherson, servicemen of the Russian armed forces used tear gas and stun grenades against the civilian population," the office of Ukraine's Prosecutor General said in a statement.
It said it was investigating the incident, and that at least four people were wounded.
Ukrainian President Volodymyr Zelenskiy praised the protests, saying in a late night address that: "I am grateful to everyone who has not given up, who is protesting, who is ignoring the occupiers and showing the marginal people who have become collaborators that there is no future for them".
Shortly afterwards, RIA news agency cited a security source as saying Ukraine had fired three rockets at the city centre but Russian occupying forces shot down two of them.
On Tuesday, Russia said it had gained full control of the Kherson region, which is strategically important as it provides part of the land link between the annexed Crimea peninsula and Russian-backed separatist areas in the east.
Kherson regional governor Hennadiy Laguta on Tuesday said the occupation meant his administration had no choice but to leave.
Thousands of people have fled Kherson to Ukraine-controlled territory, according to the local authorities, who report power and water outages, severe shortages of food and medicines and cellphone network issues in some occupied areas.
Footage shared on social media of the protest on Wednesday showed people rushing away from a square filled with drifting smoke. A loud boom rang out and a thick plume of white smoke rose into the air.
Coughing could be heard and one person could be seen clasping their hands over their eyes.
Two people, who told Reuters they had participated in the rally, said people were waving Ukrainian flags, chanting "Glory to Ukraine" and singing the national anthem when a large number of Russian forces turned up.
Speaking by phone, former factory worker Ihor, 33, said some of the Russians first fired in the air.
"There wasn't panic until they threw the tear gas grenade," said 18-year-old student Mykyta.
Both men, who gave only their first names for security reasons, said they had not seen any sign of the planned referendum being held.
Ihor said those who remained were "depressed. People understand that they can't really do anything. The police are everywhere, people are stopped everywhere," he said.
"Many Kherson residents are afraid," he said. "All the same, Kherson residents do not give up, they quietly go to rallies. They've hung up flags, blue and yellow ribbons, all in support of Ukraine."
