Signija Kalniņa, spokeswoman for Lux Express, told LTV that one of the drivers died and 13 passengers were hospitalized after the accident, with three in critical condition. The crash took place on the St. Petersburg - Riga route.
The Latvian Foreign Ministry told Latvian radio that 10 Latvians were injured in the crash, and three are still hospitalized.
According to information from the police, the crash happened as the bus collided with a truck that had moved to the opposite lane. The road in the area was slippery and covered with black ice.
Estonia's ERR reported that the bus had 19 passengers and two drivers, and on Monday morning five people are still hospitalized.
"It's very sad. This is the second serious crash involving one of our buses within 10 days. Moreover, it happened so that the crashes took place in a single region and quite close to one another," Hannes Saarpuu, board chairman of Lux Express, told rus.err.ee.
In late January another Lux Express coach on the same route crashed in eastern Estonia, injuring twelve.
