Kseniia Petrova was returning to the US from a trip to France when officials revoked her visa and detained her

On Wednesday, Cora Anderson, who works with the Russian scientist Kseniia Petrova, shared the news of Petrova’s detention on Facebook, saying the Russian scientist arrived at Boston Logan international airport on 16 February from a trip to France when she was stopped by US authorities.

According to Anderson, authorities revoked Petrova’s visa and told her that she was to be deported to Russia. In response, Petrova said that she feared political persecution and was instead sent by authorities to a detention facility, Anderson said.
