Four people were killed in an apparent gun rampage carried out by a soldier in Russian-occupied Crimea, according to local authorities installed by Moscow. Officials said the suspect was later detained.

The region's Moscow-backed governor, Mikhail Razvozhayev, said the gunman opened fire on both fellow soldiers and civilians. Initial reports described the attack as apparently random.

Crimea, which was annexed by Russia, remains a highly sensitive region politically and militarily. News of a soldier firing on people in the area is likely to raise fresh questions about security and conditions on the ground.

Few additional details were immediately available in the trimmed report, including what may have led to the shooting. Authorities said the suspected gunman had been taken into custody after the attack.
