It’s ten o’clock in the morning. The 10 members of the UNRWA distribution team watch Ahmed as he slowly walks the 100 metres that separate him from the armed soldier. A few moments later all can they see is the back of a blue UN vest confronting a green uniform. The men do not speak. They have been waiting at the Beit Iba checkpoint, five kilometres north-west of Nablus, for more than two hours, and still have a long way to go before they reach their destination.
