Ukrainian and US negotiating teams have sat down for a fresh round of talks in Switzerland with a focus on post-war reconstruction and preparing a future trilateral meeting with Russia.

The talks in the city ofGenevabegan on February 26, hours after Russian forces rained down drones and missiles on multiple Ukrainian regions -- and also after Moscow sent Kyiv bodies of people apparently killed in the now four-year long war.

"A bilateral meeting with the American delegation has begun with Steve Witkoff and Jared Kushner,"wroteUkraine's chief negotiator Rustem Umerov in a social media post.

Umerov confirmed that a "prosperity package" would be discussed, including issues such as economic support and investment -- along with "the humanitarian track and the issue of possible exchanges."

Russia and Ukraine have held numerous exchanges of prisoners and remains of killed soldiers during the conflict. On February 26, officials from the two countries said Russia had returned what it said were the bodies 1,000 Ukrainians.

The authorities in Kyiv said they "may belong to Ukrainian defenders" and that work would begin to identify them. Vladimir Medinsky, a key aide to Russian President Vladimir Putin, said Ukraine had returned the bodies of 35 Russian soldiers in exchange.

Alongside the diplomacy and the exchange, the brutal reality of the war continued.

Dozens of people are known to have been injured as a result of this attack, including children, Ukrainian President Volodymyr Zelenskyywroteon social media after an overnight barrage that he said included 420 drones and 39 missiles.

Targets included housing blocks, gas infrastructure, and electrical substations, Zelenskyy said.
