Beijing subway security stepped up after Xinjiang atttack

China has beefed up security at subway stations here after Thursday's deadly bomb attack in Urumqi, provincial capital of the restive Xinjiang province, in which 39 people were killed and 94 others injured.
Subway passengers will have to face security checks at three more stations from today, state-run Xinhua news agency reported.
Previously, only personal belongings needed to be checked when passengers entered a subway station.
In January, Beijing Subway required that passengers should also go through security check at six stations, all near the sensitive Tian'anmen Square in central Beijing.
The security measure was expanded to three more stations -- two in the city's north and one in the west, according to the Beijing Subway official.

Beijing has a population of 21 million people and the Chinese capital city has 465 kilometres of subway lines in operation. Beijing's subway carries 10 million passengers daily.

The new subway security measure comes as China at large is facing more severe challenges of violent terrorist attacks.
A terrorist bombing attack occurred at an open air market in Urumqi, capital of far west China's Xinjiang Uygur Autonomous Region, on Thursday, leaving 39 people dead and 94 others injured.
Previously, there were a string of violent attacks that shocked the country, including one at a train station in the southwestern city of Kunming in March and another one at Tian'anmen Square in Beijing in October last year.

Authorities in Beijing have launched several anti-terrorist drills over the past month, in a bid to tighten the capital's security.
