TIRASPOL, August 14 (RIA Novosti) - A six-year-old Russian girl was killed and a Russian man was wounded in an explosion that ripped apart a trolleybus in a breakaway region of Moldova yesterday, doctors said Monday.

Two people were killed in the bombing in Tiraspol, the capital of the self-proclaimed republic of Transdnestr, and 10 were taken to the hospital.

Police told RIA Novosti two grenades had detonated on the vehicle and two unexploded ones were discovered later.

The attack was the second fatal incident to strike public transport in the area in just over a month. On July 6, an explosion blew the roof off a mini-bus taxi in Tiraspol, killing seven and wounding 23.

Security services said then that the attack was linked to the criminal underground rather than terrorism.
