Russian shelling killed two children -- a brother and sister -- in the village of Druzhba (Friendship) in eastern Ukraine on Friday, the local governor said.
"At about three o'clock in the afternoon, the Russians shelled the village with artillery -- one of the shells hit the yard where the children were," Governor Pavlo Kyrylenko said on social media.
The boy was aged 10 and the girl 16. Earlier Friday, Kyrylenko said a couple had also been killed by Grad rocket fire in the city of Kostyantynivka.
