An investigation is ongoing to locate a member of the National Guard, who opened fire at a factory, killing at least five people and injuring five others.
Ukraine's interior ministry has said at least five people were killed after a member of the National Guard opened fire at an aerospace factory in the east of the country.
The shooting took place in the city of Dnipro on Thursday. The attacker opened fire with a Kalashnikov assault rifle and immediately fled the scene, the interior ministry said.
"As a result, five people died and another five were injured," the statement added.
The incident occurred around 0140 GMT (3:40AM local time) when the shooter was being issued a weapon at the beginning of a shift.
The Yuzhmash facility is an aerospace factory that produces and tests material related to defence, aeronautics and agriculture, according to its website.
The ministry said the shooter was born in 2001 and there was an ongoing operation to locate him.
"The motives for the crime are not yet known," the statement said, adding that a commander of the National Guard, Nikolai Balan, had been dispatched to the scene.
Bullying rituals plagued militaries of former Soviet countries in the 1990s, a trend which rights groups say has improved, but regularly result in suicides or murders.
