YEREVAN, Armenia (AP) _ A mine exploded early Sunday under a train heading from Georgia to Armenia, killing two people and injuring 10 others, an Armenian transportation official said.

The explosion occurred near the Georgian town of Sadakhlo, about two miles from the Armenian border, said Khachik Avetisyan, the head of the transportation service of the Armenian Railroads.

There was no immediate indication of who had planted the mine.

The region is populated mainly by ethnic Azerbaijanis, who have been fighting with Armenia for five years over Nagorno-Karabakh, a mainly Armenian enclave within Azerbaijan.

The mine, which was on a track, exploded under the last car of the train, which was heading from the Georgian capital of Tbilisi to the Armenian capital of Yerevan, Avetisyan said.

The train was able to continue to Yerevan, and the line was repaired, Avetisyan said.
