(BBC) – Ukraine says its troops on the eastern front line have come under heavy shelling during a rebel attack, with one soldier killed and four wounded.
It says four rebel soldiers were killed and six injured.
Russian-backed rebels say Ukrainian forces tried to break through their lines and got caught in a minefield, with two killed and three wounded.
Ukraine’s President Volodymyr Zelensky said the rebel “provocation” would not derail Kyiv’s course to achieve peace.
The violence puts new pressure on a shaky ceasefire deal.
Tuesday’s clash, now said to be over, took place near Zolote, a front-line village in the Luhansk region of Donbas.
The conflict began in 2014, and the rebels control large swathes of the region, including the cities of Donetsk and Luhansk.
