An Afghan police officer opened fire at foreign doctors inside a hospital in the capital Kabul, killing three members of the medical staff and injuring two more people.  The facility specialized in the treatment of disabled children and women’s maternal health issues.

Family members identify one of slain as Doctor Jerry Umanos, a doctor from Chicago who spent his career helping people in troubled areas.  He split his time between the two practices, working at a hospital on Chicago’s poverty and crime-racked South Side to earn money to afford to go to Afghanistan for several months a year.

The police officer Ainuddin, who like many Afghans goes by one name, was a two-year veteran of the police department, but had only recently been assigned to guard the hospital.  The Taliban did not claim responsibility for the attack, which raised the possibility that the police officer grew to resent the presence of foreigners on his own.  Authorities are interrogating him, trying to determine his motive.

Three weeks ago, award-winning Associated Press photographer Anja Niedringhaus was shot and killed and reporter Kathy Gannon was wounded in a shooting by another police officer in Afghanistan.  A Swedish journalist was murdered in Kabul a month before that.
