Spending your leave in a makeshift Syrian hospital
It has been estimated that around 20,000 people have died in Syria since the violence began there in March 2011.
Anaesthetist Rachael Craven gave up her annual leave from her job at Bristol Royal Infirmary to work undercover treating patients in Syria with Medecins Sans Frontieres.
She described what it was like working in intense conditions in a house which had been converted into a makeshift hospital.
The "kitchen's a sterilisation area" and "the bedrooms upstairs have been converted into wards".
