The Russian capital and its suburbs were subjected to a massive UAV raid overnight

Three Indian nationals have been wounded and one was killed in a drone strike in Moscow Region, New Delhi's embassy in Russia has said.

The incident occurred overnight amid a large-scale Ukrainian kamikaze drone raid on the Russian capital and its surroundings. The attack appears to have been the largest to affect the area in over a year.

India's embassy described the victims as "workers" but did not disclose where the attack occurred. The diplomats are now "closely cooperating with the company's management and local authorities" and providing the "necessary assistance" to the victims. 

"Today in the Moscow region, as a result of a drone attack, one citizen of India was killed and three others were injured. Embassy staff traveled to the scene of the incident and visited the victims in the hospital," the mission said in a statement.

Separately, local governor Andrey Vorobyev said that at least three civilians were killed and several wounded across Moscow Region in the strikes. It was not immediately clear whether the tally he provided included the Indian nationals.

Kiev has intensified long-range drone attacks on Russia since mid-March, sending fixed-wing UAVs in the hundreds on an almost daily basis. Moscow has condemned the strikes as "terrorist" attacks, alleging that they indiscriminately target civilian sites and infrastructure. 

Russia has been retaliating with a long-range strike campaign of its own, targeting Ukraine's dual-use infrastructure, including military manufacturing installations and energy facilities. Russia maintains it carefully selects the targets and never attacks purely civilian sites.
