Russia launched another drone attack Monday night, making the two consecutive nights of attacks the largest drone assault against Ukraine yet, coming as peace talks between the nations stall.

Russia launched hundreds of Geran drones and over a dozen missiles of various types at targets across Ukraine on Monday night, with a large number hitting Kyiv. The Ukrainian Air Force claimed Russia launched 315 drones and seven missiles, 284 of which were intercepted or redirected via electronic warfare. The high number of interceptions is unlikely, however, given the number of identified strikes and Ukraine’s recent problems with its air defences. Open-source intelligence analysts identified at least 28 targets hit in Kyiv alone shortly after the strikes.
