The Chinese Consulate in New York says a Chinese national is the third person killed in the Boston marathon blasts.

An official at the consulate's press section, who was not authorized to give his name, said that one Chinese student was injured and another died in the blast.

The official said a work group from the consulate was in Boston to investigate the situation and assist relatives of the victims.

The official Chinese news agency Xinhua reported that relatives have requested that the deceased not be identified.
