By HANNA ARHIROVA and DASHA LITVINOVA (Associated Press) KYIV, Ukraine (AP) — Fierce fighting raged Thursday in southeastern Ukraine, where a Western official said Kyiv has launched a major push and Russian President Vladimir Putin said “hostilities have intensified significantly.” Battles in recent weeks have taken place on multiple points along the over 1,000-kilometer (600-mile) front line as Ukraine wages a counteroffensive with Western-supplied weapons and Western-trained troops against Russian forces who invaded 17 months ago. Putin praised the “heroism” with which Russian soldiers were repelling attacks in the Zaporizhzhia region of the southeast, claiming Moscow’s troops not only destroyed Ukraine’s military equipment but also inflicted heavy losses to Kyiv’s forces. He insisted on state TV that Ukraine’s push in the area “wasn’t successful,” although it was not possible to independently verify his claim.
