Ukraine Says Not Interested In Taking Over Russia's Kursk Region

"These Ukrainian actions are absolutely legitimate," Ukrainian foreign ministry spokesperson Georgiy Tykhy told a press conference.

Ukraine said Tuesday it would not hold on to Russian territory captured in its surprise cross-border incursion and offered to stop raids if Moscow agreed a "just peace".

Ukrainian forces entered Russia's Kursk region last Tuesday, taking over two dozen settlements in the biggest attack by a foreign army on Russian soil since World War II. Russia said Tuesday it had fended off new attacks in Kursk.

More than 120,000 people have fled the area and Ukraine's military chief Oleksandr Syrsky said Monday that his troops controlled about 1,000 square kilometres of Russian territory.
