BEIJING - China said Thursday it opposes all violence.

Foreign Ministry Spokesman Liu Weimin made the remark when asked to comment on an Iranian nuclear expert's death.

Liu said at a regular press conference that he had noted relevant reports.

A bomb attack killed an Iranian nuclear scientist and his driver in northern Tehran on Wednesday. Local reports identified the dead passenger as Mostafa Ahmadi-Roshan, a staff member at Iran's Natanz nuclear enrichment site.
