Explosions rocked two Internet cafes in central China, killing two people, injuring four and leaving the premises spattered with blood and broken glass, a local official and state media said Saturday.
Authorities refused to say if bombs were involved in the blasts, which occurred Friday night about 10 minutes apart at two cafes within about 33 feet of each other in Hefei, the capital of Anhui province. No motive was apparent for an attack on the premises.
Such incidents are rare in China, although explosives are widely available and reports of their use in criminal acts have risen in recent years.
