JERUSALEM, 30 April (IRIN) - Increased Israeli restrictions on the checkpoints around East Jerusalem have caused more delays and more lost man hours for UN staff in March 2008 than in all of 2007, the UN's Office for the Coordination of Humanitarian Affairs (OCHA) has reported. In the Humanitarian Monitor for March, released on 24 April, OCHA said "operations were significantly affected" and almost daily UN vehicles were delayed and even turned back by Israeli soldiers at checkpoints south of Jerusalem.
