Russia's Defense Ministry has claimed that Ukrainian forces launched a large-scale offensive against five areas in the Donetsk region of eastern Ukraine on Sunday, but their forces were able to successfully thwart the attack. The Ukrainian government has not confirmed or denied the claims, but have cautioned against Russian misinformation. The conflict between Ukraine and Russia has been escalating since 2014, and the recent attack is the latest in a series of escalations. It remains to be seen how the two sides will respond.
