(Reuters) -Ukraine brought home a new group of prisoners of war from Russia on Wednesday, President Volodymyr Zelenskiy said, saying it brought to more than 1,000 the number of returning soldiers as agreed at talks in Turkey. Zelenskiy, writing on the Telegram messaging app, said those returning were ill or seriously wounded.

Russia and Ukraine discussed further prisoner swaps on Wednesday at a brief session of peace talks in Istanbul, but the sides remained far apart on ceasefire terms and a possible meeting of their leaders.

The two sides made little progress toward a ceasefire — despite President Trump's threats of harsh new economic penalties on Moscow should it fail to agree to a deal by early September.

Kyiv and Moscow will hold a new round of peace talks — the first in seven weeks — on Wednesday in Turkey, Ukrainian President Volodymyr Zelensky said.

The next set of peace talks between Ukraine and Russia - the first meeting in seven weeks - is planned for Wednesday in Turkey, Ukrainian President Volodymyr Zelenskiy quoted the head of Ukraine's National Security and Defence Council as saying on Monday.

With Trump now open to supplying U.S.-made weapons to Ukraine, Gen. Oleksandr Syrsky calls for longer-range missiles and the permission to use them against Russia.
