A Russian glide bomb struck a village in eastern Ukraine on Tuesday as people waited in the open air to collect their monthly pension. The blast killed at least 24 people and injured 19 others, the Ukraine Emergency Service said.

The bomb hit the Donetsk region village of Yarova at around 11 a.m. local time, authorities said. The village lies less than 10 kilometers (6 miles) from the front line. Donetsk regional head Vadym Filashkin said 23 of the dead were pensioners.

Footage released by the Donetsk regional police force showed trees snapped in half around the village square and a crater where the bomb hit.

Bodies of the victims were lined up on stretchers in a makeshift morgue.

It was the latest Russian attack to kill civilians.

More than 12,000 Ukrainian civilians have been killed in the three-year war, the United Nations says.

With U.S.-led peace efforts making no headway in recent months, Russia has escalated its aerial barrages of Ukraine.
