Ukraine's government claims "step by step" advances demonstrate the ambitions of its military, moving "deep into Kherson" with the aim of re-taking the southwest city from Russian forces "by September".
Kherson was the first Ukrainian city to fall to Russia in the current conflict and is a key Russian launching point for strikes on surrounding areas.
Ukraine's military says it's been gaining momentum along Kherson's northern and western borders in recent weeks, with the help of Western supplied mobile rocket and artillery launchers boosting its capabilities.
Ukraine's government is urging Kherson residents to get out of the city as soon as possible.
Dmytro Davydenko a Humanitarian Coordinator from Mykolaiv says: "The number of attacks now is bigger - higher. A good recommendation is for people to leave the city."

"We have an opportunity," Vitalii Kim the Governor of Mykolaiv Oblast has said." We see the difference between now and a month ago and we are preparing and counter-attacking already."
Mykolaiv has repeatedly fought off Russian military advances as the ship-building, industrial port city comes under almost daily missile and artillery attack.
As the conflict's third hardest-hit Ukraine city, local officials report Mykolaiv has gone only 25 days without strikes since February 24th.

The same officials estimate around 8,000 buildings and structures have been hit by Russian land, air and sea strikes including homes, administrative buildings, hotels, universities, humanitarian centres, grain stores and ports.
Half of Mykolaiv's 500,000 residents have fled the city and those who remain have been without drinking water since April when the city's main water supply pipe was damaged in fighting.
For bathing, residents rely on salty "technical water" pumped to homes from nearby rivers.
Recent Russian military advances have been concentrated in Ukraine's eastern Donbas region. Military analysts predict a necessary Russian military "pause" following those advances may present Ukraine's army with an opportunity and advantage.
