 Ukraine plans its counter-offensive in southern direction in May. The Ukrainian armed forces plan to launch their long-awaited counter-offensive in the southern theater of operations next month. The New York Times reported, citing leaked Pentagon documents. According to the newspaper, Ukraine will prepare 12 brigades of about 4,000 servicemen each by the end of April to launch the counter-offensive in the southern direction. The Western countries are now training and supplying 9 of the 12 brigades, according to the New York Times. The American officials believe it is unlikely that the counter-offensive will lead to big gains and the drastic change in the situation on the battlefield. The topic of Ukraine's potential counter-offensive has been constantly brought up by the media in recent months. The Russian Foreign Ministry earlier said that the Western countries' open discussions of the upcoming Ukrainian counter-offensive proved their direct involvement in the conflict. The US media reported earlier that the Pentagon and the US Department of Justice had launched a probe into the leak of secret documents about Washington and NATO's plans to train Ukrainian soldiers ahead of an offensive against Russia. Numerous documents on the schedules of armed supplies and the strength of the forces were leaked to social networks, including Twitter and Telegram. Jack Terrier, 21, a member of the Massachusetts Air National Guard, was arrested on April 13 in connection with the leak case.
