A gunman opened fire yesterday in a Russian Orthodox cathedral on the island of Sakhalin, off Russia's eastern coast, killing a nun and a churchgoer and wounding six other people, officials said.
The shooting happened as Russian security forces are on high alert due to concerns about possible attacks on the Winter Olympics in Sochi, thousands of kilometres to the west. There was no apparent link to the Winter Games.
The gunman was detained at the scene after the shooting at the main cathedral in the city of Yuzhno-Sakhalinsk on the island in the Sea of Okhotsk, north of Japan, the federal investigative committee said.
It added that the suspect had worked as a security guard in Yuzhno-Sakhalinsk, some 6,650 kilometres from Moscow.
There was no immediate word on a motive for the attack, which came six days after a Moscow teenager killed a teacher and a policeman and held classmates hostage in the first major school shooting in Russia.
Most of the wounded in yesterday's mid-afternoon attack were shot in the legs and their lives were not in danger, RIA cited the regional leader of the Russian Orthodox Church, Archbishop Tikhon, as saying.
He said a prayer service for the victims would be held at the cathedral, which is the main Russian Orthodox church in a region that includes Sakhalin and the Kurile island chain.
The part of the church where the shooting took place would have to be cleaned of victims' blood and blessed, he added.
There have been a handful of shooting sprees in offices and public places in Russia in recent years, but they are relatively rare and state-run media tend to treat such attacks as a largely American phenomenon.
The February 3 shooting at a Moscow school, in which a student used his father's rifles, has led to calls for stiffer punishment for gun owners whose weapons are used in attacks.
