Mobile phone coverage switched off in Moscow metro

Mobile phone coverage has been switched off in the Moscow metro at the Federal Security Service (FSB)'s order following a terrorist threat warning, a Moscow law enforcement source told Interfax on Thursday.

The source said the measure has been taken repeatedly and proven to be efficient in obstructing communication between possible terrorists.

In particular, mobile coverage was earlier switched off in the area of an antiterrorist raid during the Moscow theater hostage crisis in 2002 and following a bombing in the metro near Avtozadovskaya station, he said.
