Ukraine's President Volodymyr Zelenskyy has warned that Russia may take the provocative step of putting Ukrainian soldiers on trial as the war-torn country marks 31 years of independence next week.
According to Zelenskyy, Russia is planning to hold a public trial of Ukrainian combatants kidnapped during the siege of Mariupol on Wednesday, to coincide with the country's independence day.
Ukraine's Independence Day, August 24, will also mark six months since Russia invaded Ukraine, resulting in a devastating war that has killed thousands.
“If this despicable show trial takes place, if our people are brought into these settings in violation of all agreements, all international rules, there will be abuse,” Zelenskyy warned in an evening address on Sunday.
“This will be the line beyond which no negotiations are possible.”
The capital, Kyiv, has already announced a ban on public gatherings. Kharkiv too declared a curfew around the holiday.
Zelenskyy was returning to a subject he had already raised in the previous night’s remarks.
“Russia could try to do something particularly disgusting, particularly cruel,” he warned late on Saturday.
“One of the key objectives of the enemy is to humiliate us” and “to sow despondency, fear and conflict”.
But he added: “We have to be strong enough to resist all provocation” and “make the occupiers pay for their terror”.
A presidential adviser, Mykhaylo Podolyak, said Russia could intensify its bombing campaign.
“Russia is an archaic state that links its actions to certain dates, it’s an obsession of sorts,” the Interfax-Ukraine news agency quoted him as saying.
“They hate us and will try to increase … the number of bombings of our cities including Kyiv with cruise missiles,” Podolyak added.
Kyiv authorities on Sunday banned public gatherings from August 22 to August 25.
In the northeastern city of Kharkiv, the regional governor announced a curfew from the evening of August 23 to the morning of August 25.
“We will not allow any provocation by the enemy. Be as vigilant as possible during our independence holiday,” Oleg Synegubov wrote on Telegram.
Kharkiv has been under regular Russian bombardment for weeks and on Sunday emergency services said a woman was killed and two other civilians were wounded in overnight raids.
Four civilians were reported killed by Russian fire in Donetsk, said the region’s pro-Kyiv governor, Pavlo Kyrylenko.
Five cruise missiles were fired at Odesa from the Black Sea, a regional administration spokesman said. Two were shot down by air defences and three hit a silo without causing injury.
