SITUATION REPORT
A calculated or unintentional return to sustained hostilities looms as Moscow and Kyiv sabre-rattle over eastern Ukraine. After Russian troops failed to leave the Russia-Ukraine border region following the completion of training exercises on 23 March, U.S. European Command elevated its watch level to “potential imminent crisis,” its highest threat level.
On 26 March, four Ukrainian soldiers were killed near the separatists' de facto capital of Donetsk, marking the most intense fighting in recent months, with cease-fire monitors reporting more extensive artillery and more advanced weaponry being used. Russian-aligned separatists and Ukrainian forces have been engaged in low-intensity conflict since Russia’s annexation of Crimea in 2014. The U.S. estimates that there are currently approximately 80,000 Russian troops amassed in Crimea and around Ukraine, nearly double Russia’s force posture in early March. The recent Russian military buildup has sparked fears that the frozen conflict on Europe’s eastern flank is heating up.
