The commander-in-chief of Ukraine's armed forces Oleksandr Syrsky said on Sunday that the position on the frontline had deteriorated and that Russia had made a number of battlefield gains.
Russia has been "attacking along the entire front line" and has achieved "tactical success in some sectors", Syrsky posted on the social media platform Facebook.
Ukraine is consulting with partners to ensure it received ammunition, weapons and other military equipment as soon as possible, Syrsky added.
Russia has made no responses to the Ukrainian statement so far.

Palestinian protesters and the Israeli army in the West Bank engaged in a tense stand-off on Wednesday as Palestinians commemorated the 76th Nakba day or the "day of catastrophe" in the mist of the intense fighting in Gaza that has displaced over one and a half million people.
Nakba Day is observed annually on May 15 by Palestinians to remember the expulsion of hundreds of thousands of Palestinians from their homes after the establishment of Israel in 1948.
The anniversary often brings heightened tensions as Palestinians believe that their ancestors were displaced from their homeland. Israel stands on territory given to the Jews by Great Britain in return for their support in World War I. But Palestinians have always claimed the land is historically theirs.
Palestinians live in the West Bank under Israeli military rule and Israel controls the borders and areas in which Palestinians can build homes.
Under Jewish law, commemorating Nakba Day is illegal.
"That's against the Israeli law, but as far as the Palestinian law is concerned and as far as the culture of Palestine, the history of our people, and the pride of every Palestinian is to mark this day. Every Palestinian is doing this in defiance and also challenging the Israeli laws," said Sabri Saidam, deputy Secretary General of the Fatah Central Committee.
Saidam believes the only path towards peace is a two-state solution.
"There is no way on this land but to achieve co-existence. The future is dependent on the fulfillment of U.N. resolutions and on adherence to international law. There's no one party that can throw the other into the sea. There's no one people that can throw the other into the sea. So we will have to invest in trying to convince Israelis at large that their government is not doing them any favor. And those who claim to be the friends of Israel and are supporting the genocide that Israel is committing right now as we speak are not true friends, because your friends would tell you where the right path is. And the only right path is the establishment of a Palestinian state," said Sabri Saidam.
Palestinians say this year's anniversary is more important than ever as they claim a present-day Nakba is taking place in Gaza.
