Russia and Ukraine will hold new peace talks on Wednesday as a follow-up to two rounds in Istanbul that made little progress on ending their war, President Volodymyr Zelensky announced.
"Today, I discussed with [Ukrainian Security Council chief] Rustem Umerov the preparations for the exchange and another meeting in Turkey with the Russian side. Umerov reported that the meeting is scheduled for Wednesday," Mr Zelensky said in his daily address.
He added that more details would be released tomorrow.
A senior Ukrainian official, speaking on condition of anonymity, told AFP earlier that the talks would probably be in Istanbul and focus on further prisoner exchanges and a possible meeting between Mr Zelensky and Russia's President Vladimir Putin.
Both sides met in Istanbul on 16 May and 2 June amid US pressure to agree a ceasefire. Despite the urging of US President Donald Trump, no breakthrough was made.
Ukrainian and Russian negotiators have so far only agreed to hold prisoner exchanges. And Russia has since launched intense air attacks on Ukraine and seized more frontline territory.
Russia has demanded Ukraine give up four regions, on top of Crimea, which it annexed in 2014. The Kremlin also insists Ukraine give up any idea of joining the NATO military alliance.
Ukraine has rejected the demands and expressed doubt that Russia wants a ceasefire.
After Mr Trump last week gave Russia 50 days to negotiate a deal or face heavy sanctions - and also renewed arms supplies to Ukraine - the Kremlin said it was ready for more talks.
The two sides exchanged ideas at the earlier talks on what a peace deal could look like, but remain far apart.
"A lot of diplomatic work lies ahead," Kremlin spokesman Dmitry Peskov told reporters, commenting on the prospects for a breakthrough.
Meanwhile, at least one person was killed in Kyiv as Russia launched 426 drones and 24 missiles in an overnight air attack on Ukraine, according to officials.
Ukraine's air force said that Russia launched 426 drones and 24 missiles overnight.

It downed or jammed 224 drones and missiles, while another 203 drones disappeared from radars, most likely having been jammed by electronic warfare, the air force said.
At least one person was killed and multiple fires were caused in the capital Kyiv, city officials said.
Kyiv Mayor Vitali Klitschko said rescuers and medics were working on sites across four districts of the capital. A subway station in central Kyiv, commercial property, shops, houses and a pre-school were damaged, city officials said.
In another tense night for Kyiv residents, many rushed to take shelter in underground stations. Explosions were heard across the city as air defence units engaged in repelling the attack.
Oleh Synehubov, the governor of the Kharkiv region, reported multiple explosions in Kharkiv, the country's second-largest city, but gave no immediate details on the damage.

Ukrainian drone attacks sow chaos at Moscow's airports
Meanwhile, Ukrainian drone attacks on Russia sowed chaos at major airports serving Moscow today, with thousands of passengers waiting in lines or sleeping on the floor after flights were cancelled or delayed, Russian media reported.
Videos published by Russian media showed people sleeping on the floor of Sheremetyevo, Russia's busiest airport by passenger numbers, amid long queues.
Russia's defence ministry said it had downed 117 drones overnight, including 30 over the Moscow region, after downing 172 drones, including 30 over the Moscow region, the previous day.

Russia's civil aviation authority, Rosaviatsiya, briefly imposed restrictions on flights overnight at Moscow's main airports - Sheremetyevo, Vnukovo, Domodedovo and Zhukovskiy.
Several thousand people were stranded in the far east of Russia due to the cancellation of flights in European Russia, while extra trains were put on to bring passengers back to Moscow from the northern Russian city of St Petersburg, Russian media said.
Moscow and its surrounding region has a population of at least 21.5 million.
