Key Takeaways from the ISW:

• The Kremlin’s unilateral short-term, theater-wide ceasefire over the Orthodox Easter holiday came into effect at 1600 local time on April 11, and both Ukrainian and Russian sources accused each other of limited violations in the first hours of the ceasefire.
• The Russian Federal Security Service (FSB) has reportedly taken control of seven of eight Russian pre-trial detention centers (SIZOs) as part of the Kremlin’s broader effort to strengthen the internal security apparatus.
• Available independent reporting indicates that Russia’s systematic use of short-range first-person view (FPV) drones against civilians in Ukraine is likely partially responsible for the increase in civilian casualties in the war in Ukraine.
• Ukraine and Russia conducted civilian prisoner and prisoner of war (POW) exchanges on April 11.
• Ukrainian forces recently advanced in the Kostyantynivka-Druzhkivka tactical area and in the Hulyaipole and Novopavlivka directions.
