JAKARTA - Ukraine has achieved "a lot" in attacks on Russia's Kursk territory, but it is difficult to say how the situation will develop next, North Atlantic Treaty Organization (NATO) Secretary General Jens Stoltenberg said on Thursday.

"Only Ukraine can make the necessary difficult choices, such as where deploying their troops and what kind of war is right in this situation," Stoltenberg said.

Russian troops advanced in eastern Ukraine, while Ukrainian troops have carried out a bold attack on Russia's Kursk territory, where on August 6 launched the largest cross-border attack on Russia since the Second World War.

Stoltenberg said Ukraine has the right to self-defense, including with long-range missiles that can achieve military targets in Russian territory.

"I'm glad many NATO countries have given that opportunity, and those who still have boundaries have softened those boundaries so that Ukraine can defend itself," Stoltenberg said.

Stoltenberg previously said at a conference he saw no direct military threat to NATO countries but said there was a constant danger of terrorism, cyber attacks and sabotage.

Meanwhile, Ukrainian President Volodymyr Zelensky will attend a meeting of the Ramstein group on Friday, a coalition of countries supplying weapons to Ukraine, where he is expected to request an increase in arms shipments, particularly long-range missiles, according to German magazine Spiegel.

President Zelensky is known to have called on allies to assist with air defenses and remove restrictions preventing Kyiv from using donated weapons for long-range attacks on Russia.
