Ukrainian drone injures 3 inside Russia
Three people were injured in an explosion in the Kireevsky district of the Tula region on Sunday, Yekaterina Makarova, press secretary of the region's Ministry of Health, told Interfax.
Russian authorities and law enforcement agencies said a Ukrainian drone with ammunition caused the explosion in the town far from the two countries' border.
Kireevsk is about 180 miles from the border with Ukraine and 110 miles south of Moscow.
The Russian state-run news agency Tass reported authorities identified the drone as a Ukrainian Tu-141. The Latvia-based Russian news outlet Meduza reported that the blast left a crater about 50 feet in diameter and 16 feet deep.
