YEKATERINBURG, November 27 (RIA Novosti) - A man who blew himself up on a commuter train in Russia's South Urals on Tuesday morning has died of his injuries, a local Federal Security Service (FSB) spokesman said.

The man blew himself up after ticket collectors asked him to show his ticket. Other passengers were not injured in the incident.

The Russian Railways monopoly said earlier, "An unknown passenger detonated what looked like a grenade on a commuter train near the Asha station at 6:50 a.m. Moscow time (3:50 a.m. GMT)."

The company said the train car was slightly damaged and its windows shattered. The incident did not cause delays to the train schedule.

The motive behind the explosion is not immediately clear.
