(IRIN News) –¬†Humanitarian needs in Yemen are huge, but it is also recognised as one of the most difficult places in the world for aid workers to operate in. What to do? ..”A wounded man arrives, accompanied by an armed and agitated companion who holds a gun to the doctor’s head as his friend is treated. Relatives bring in a girl with severe burns, and proceed to threaten and assault medical staff who they think are not treating her quickly enough. MSF staff are held to ransom by a family demanding compensation for the costs of taking a member to Egypt after local treatment failed.”
