Karachi, Pakistan - Gunmen on motorcycles opened fire on a bus in Pakistan's southern city of Karachi on Wednesday, killing at least 43 people, police said, in the latest attack directed against religious minorities this year.
Television channels carried pictures of a pink bus covered in bullet holes and lines of waiting ambulances.
"There were six attackers. They boarded the bus and carried out the shooting," Police Superintendent Najib Khan told Reuters.
He said all the passengers were from the Ismaili community, a minority Shi'a Muslim sect in majority-Sunni Pakistan.
