SACRAMENTO, Calif. - Lyudmila Lopeshkova can't believe the bombings in Russia she sees on television happened in her home town.

Lopeshkova moved to Sacramento from Volgograd, Russia in 2000, when she was just 6 years old. But she fondly remembers growing up with her older siblings there, playing in the street and staying out after dark.

"I'm very shocked, especially when it's coming from my city," she said.

Some of Lopeshkova's relativesstill live in Volgograd. Over the weekend, 31 people were killed in two suicide bombings in the city - one on a bus and one in a train station. Dozens more were injured.

"You wouldn't assume that someone would try to bomb a small city like that, and it's really shocking and upsetting because I grew up there,"Lopeshkova said.

Lopeshkovasaid she hasn't heard from her family in Volgograd since the bombings.

"I really want to know, I hope it's none of them, that's not something that I would want coming into the new year, hearing that one of [my] family members died in something like this."

There has been no claim of responsibility for the attacks, but some say the bombings show a security threat to the upcoming Winter Olympics in Sochi, Russia. Volgograd is a rail hub for people making the trip to Sochi.
