KYIV (Reuters) -Russia launched 60 drones at Ukraine overnight, injuring several people, officials in Kyiv said on Tuesday, indicating a sharp decrease in the intensity of Moscow's attacks after it conducted three nights of massive aerial bombardment.

The earlier attacks - which the Ukrainian Air Force said included a record barrage of 355 drones on Sunday night - prompted U.S. President Donald Trump to say that Russian President Vladimir Putin had "gone absolutely CRAZY" and threaten sanctions.

The air force said Russia's latest drone attack hit targets in nine locations and used 60 drones. A 17-year-old boy was among 10 people who were injured overnight and early on Tuesday, officials said.

"Air defence forces were working during the night in Dnipropetrovsk," Serhiy Lysak, governor of the central-eastern region, said on the Telegram messaging app.

The latter attack sparked a fire in a private house and an outbuilding in one district and destroyed an agricultural enterprise, a private house and a car in another, he said. 

A 59-year-old man was injured in a morning drone attack on the southern city of Kherson, the military administration said, while in a separate drone attack close to 8 a.m. (0500 GMT), six city employees were injured.

The city regularly comes under Russian shelling and drone attacks.

In the northeastern city of Sumy, a drone strike sparked a fire in a building of an industrial enterprise. An airstrike damaged at least seven private and one two-storey buildings and cars in another area, the military administration said. There were no casualties, it added.

Russia, which began its full-scale invasion of Ukraine in February 2022, did not immediately comment on the reports.

Ukrainian President Volodymyr Zelenskiy has repeatedly called for the West to step up sanctions pressure on Russia to force it to accept the need for peace.
