GROZNY, June 22 (RIA Novosti) - Russia's Prosecutor-General's Office has opened an investigation into the disappearance of 11 people following a special operation in a village in Chechnya.

Nikolai Khazikov, the head of the investigation, told a news conference at Severny airport in the Chechen capital, Grozny, that a case had been opened into kidnapping and extortion following events in the village of Borozdinovskaya, northeastern Chechnya, on June 4.

As a result of a special operation, 11 people were abducted and transported to an unknown location. Their fate remains unclear.
