(NEW YORK) — More than a year after Russian President Vladimir Putin launched a full-scale invasion of neighboring Ukraine on Feb. 24, 2022, the countries are fighting for control of areas in eastern and southern Ukraine. Ukraine has begun its long-awaited counteroffensive against Russia, officials told ABC News.

Multiple reports have said a major battle has begun in southeastern Ukraine, south of the major Ukrainian city of Zaporizhzhia.

Counteroffensive begins in southeastern Ukraine, south of Zaporizhzhia

Arguably, Ukraine’s counteroffensive was getting going a few days ago, and the Institute for the Study of War said as much on Monday, saying on Twitter that “Russian and Ukrainian officials are signaling the start of the Ukrainian counteroffensive.”

However, there were significant developments on Thursday. Multiple reports said a major battle has begun in southeastern Ukraine, south of the major Ukrainian city of Zaporizhzhia.

Well-placed unofficial pro-Ukrainian sources said the southeastern front is becoming more active and there are unconfirmed images and reports that Ukraine’s new modern German-made Leopard 2 tanks are involved in the offensive.

“The events that are happening now on the front line signal the start of the offensive and Ukraine will intensify its efforts,” the head of Russia’s Wagner mercenary group, Yevgeny Prigozhin, said Thursday morning.
