Beijing beefs up transit security in wake of Moscow bombing

BEIJING, March 30 (Xinhua) -- Beijing Tuesday beefed up security in the city's metro system, said a senior public security officer.

Fu Zhenghua, director of the Beijing Public Security Bureau, confirmed the security in the capital city had been increased after the double suicide bombing in Moscow's subway Monday.

"Police patrols aided with sniffer dogs were increased at metro stations, where police would make more frequent inspections and cross-question suspicious passengers," he said.

He added that Beijing had maintained tight transit security since the 2008 Beijing Olympics.
