An employee of the Ukrainian State Border Service was injured in an overnight attack, Head of Luhansk Regional Military-Civilian Administration Heorhiy Tuka has said.

"The sound of gunfire was again audible in Stanytsia Luhanska at night. Border guards' trailers were damaged. One border guard suffered injuries," Tuka wrote on Facebook on Monday morning.

"Here is the answer to your question 'when [the checkpoint] may open'," he said.

The Stanytsia Luhanska checkpoint was temporarily shut down on April 8 due to the shelling incidents in the area. It is a pedestrian checkpoint, which is not equipped to clear vehicles. After the shutdown of the Zaitseve checkpoint amid constant attacks, the checkpoint was the only one operating in the region. The other three functioning checkpoints in the anti-terrorist operation zone are located in Donetsk region.
