Metro Head Says 2 Blasts Prevented

Moscow metro chief Dmitry Gayev said Thursday that vigilant passengers had prevented two large explosions, RIA-Novosti reported.

"Thanks to the timely information provided by passengers, the explosives were successfully removed before they went off," Gayev said, RIA-Novosti reported.

He gave no details of the timing of the planned blasts or their locations. He described the explosives as "very serious."

Telephone calls to the metro press service for further comment went unanswered Thursday. Police could not confirm the report.

Gayev said a device to detect chemical and biological weapons would be soon placed in the Belorusskaya metro station on the circle line as a precaution against a possible terrorist attack. "We will soon open this experimental site to learn how this equipment to detect chemical and biological weapons works," Gayev said.

He also said metro officials were considering placing metal detectors in every metro station.

A bomb exploded on a crowded train car traveling between the Avtozavodskaya and Paveletskaya stations in February last year. Forty-one people died.

Some 8.5 million passengers use the subway system every day, making it the world's busiest.
