Human rights groups have expressed mounting concern about a security crackdown under way in Bahrain.
Physicians for Human Rights (PHR) says there have been attacks on physicians, patients and unarmed civilians since protests began in February.
It says at least 32 medics have been arrested – some by masked men in the middle of the night. It believes they were targeted because they have seen evidence of abuses by security forces.
The government denies the reports.
