A jury has determined that a British doctor who died in a Syrian prison last year was a victim of unlawful killing.

The case involves the death of 32-year-old Abbas Khan in December.

The London jury said Monday that he had been intentionally killed without any justification. His family has long claimed he was murdered while in custody.

Syrian officials had maintained that the orthopedic surgeon had hanged himself in his jail cell.

Chief Coroner Peter Thornton said Khan had traveled to Syria to use his medical skill to help people there during the country's civil war.
