Some residents of Brighton Beach in Brooklyn are expressing concern for family members and friends back home in Russia after more than 30 people were killed in explosions.
A suicide bomber killed 14 people aboard an electric bus in the southern Russian city of Volgograd during the Monday morning rush hour, and authorities believe it was the work of the same group that set off a bomb at the railway station a day earlier.
Some Bright Beach residents who spoke with NY1 said they feared this is just the beginning of the violence.
"Personally, I feel like it's the start of many, especially with the Winter Olympics coming up in Sochi,” said one resident.
"I think it's also to attract attention because of the Olympics and because of the New Year coming, which, incidentally, is a very big event in Russia. Always has been, traditionally,” said another.
"We have to be careful and if we see something, we have to say something. It works for everybody all over the world, I think,” said a third.
The United States released a statement denouncing the attacks and said it would welcome "closer cooperation" with Russia on security preparations in the run up to February's games.
