Russia has said it intercepted drones bound for Moscow after warning of a potential retaliatory strike on Kiev despite a two-day unilateral ceasefire it declared around its World War 2 victory holiday.
Ukraine had blasted Russia's temporary truce as a propaganda measure to protect the victory parade on Friday — one of the most important patriotic events for Russian leader Vladimir Putin.
Hours before Russia's ceasefire began, Ukrainian President Volodymyr Zelenskyy warned allies of Russia against attending the parade.
"We have also received messages from some states close to Russia, saying that their representatives plan to be in Moscow... A strange desire... in these days. We do not recommend it," Zelenskyy said.
"They want from Ukraine a permit to hold their parade so that they can go out onto the square safely for one hour once a year, and then go on killing," the Ukrainian leader added.
Zelenskyy had earlier proposed a counter-truce from May 6 that has gone unheeded.
With Moscow doubling down on its attacks on Ukraine in the last days, Kiev has struck back.
Russia's defence ministry said on Thursday that its forces had destroyed almost 350 Ukrainian drones overnight.
Another 20 were intercepted in the two hours after Moscow's truce began, according to a series of updates by city mayor Sergei Sobyanin posted on Russian social media Max.
The Russian defence ministry had, in turn, urged residents and diplomats to leave Kiev, threatening a potential retaliatory strike in case of a Ukrainian attack during its ceasefire.
"We remind the civilian population of Kiev and staff at foreign diplomatic missions once again of the need to leave the city in good time," the ministry said in a statement.
That followed a similar warning by the foreign ministry issued late on Wednesday, calling on diplomats to evacuate.
During the truce, Russia's defence ministry said it would "completely" halt fire along the frontline and stop long-range strikes on military infrastructure. If Ukraine did not follow suit, Moscow would respond "in kind", the ministry said.
Guests at parade
Russia marks WW2 Victory Day each year on May 9 with a massive military parade through Red Square.
In recent weeks, Kiev, which has expanded its drone capabilities, has stepped up strikes on Moscow and deep inside Russia, hitting targets hundreds of miles from Ukraine.
The attacks have created unease in Russia ahead of the parade, normally a grand show of force displaying tanks and missiles, which marks the Soviet victory over Nazi Germany.
Moscow has said it will omit military hardware from the procession for the first time in almost 20 years.
The number of foreign guests has also shrunk — only the leaders of Belarus, Malaysia and Laos will attend, apart from leaders of two Russia-backed Georgian breakaway republics, according to the Kremlin.
Moscow has also started intermittent city-wide internet shutdowns lasting until Saturday.
Talks on ending what has spiralled into Europe's worst conflict since World War II have shown little progress and have been sidelined by the Iran conflict.
Moscow is demanding that Ukraine withdraw from four regions it claims as its own — terms seen as unacceptable to Kiev.
