Ukraine is "preparing very important counteroffensive steps," Ukrainian President Volodymyr Zelensky said, but added that the country needs more time, CNN has reported.
"We really need some more time. Not too much," before launching the much-anticipated counteroffensive, Zelensky told journalists after he met with British Prime Minister Rishi Sunak at the Chequers estate in southeast England.
He declined to share dates.
Russia's war in Ukraine is at "a pivotal moment," Sunak said.
"Russia has conducted an unprovoked and illegal attack on Ukrainian people. It is carrying out horrific war crimes… The UK will remain steadfast in supporting Ukraine and its people to defend itself against that aggressions," he added.
Earlier on Monday, the British government announced a new package of military support for Ukraine, which will include "hundreds of air defense missiles" and "hundreds of new long-range attack drones," according to a statement.
