Ukraine's invasion of the Kursk region has allowed Kyiv to seize the battlefield initiative for the first time since the end of last year, a leading thinktank has said.
The US-based Institute for the Study of War (ISW) said that since November 2023 Russia has been able to "determine the location, time, scale and requirements of fighting in Ukraine".
However, the continuing invasion of the Kursk region by Kyiv's forces "has forced the Kremlin and Russian military command to react and redeploy forces and means to the sector".
