A suspected female suicide bomber killed three Chinese teachers in Karachi on Tuesday, police and officials said, drawing strong condemnation from Beijing, in the first major attack this year against nationals of long-time ally China working in Pakistan.
The three were among passengers on a minibus returning to Karachi university after a lunch break when the bomb exploded at the entrance to the university's Confucius Institute, killing the Chinese teachers and a Pakistani national, police and officials said.
