A third person has died as a result of a Ukrainian drone attack on the Moscow region, Evgeniya Khrustaleva, the head of the town of Domodedovo, said on Tuesday via her channel in Telegram.

Massive drone strikes on Moscow left a trail of destruction in residential areas in Ukraine’s largest ever attack on the city according to local officials. The attacks come as the U.S. and Ukraine delegations are engaged in pivotal negotiations in Saudi Arabia over a possible minerals deal in exchange for security guarantees.
