Two dead in China 'suicide' blast

Two people have died in a blast at a railway station in central China, which state media has described as a suicide bombing.

Three people were injured in the explosion, which happened on Friday morning in Zhengzhou, Henan province.

Xinhua said seven people had been "put under control" and further investigation was under way.

Suicide has become an increasingly common form of protest for Chinese people who feel disenfranchised.

The blast shattered ticket windows on the first floor of the ticket-selling hall of the station, Xinhua said.

The explosion happened two days after Premier Wen Jiabao visited railway employees in the city on the eve of the lunar New Year festival, the agency said.
