It is from information given to me by a friend at the Begin Sadat Institute:
Humanitarian Aid
Contrary to Hamas propaganda on the siege of Gaza, in fact there are no limitations on the
import of goods except weapons and certain dual-use items (for example chemical
fertilizer is a major ingredient for manufacturing explosives).
From 8 July, when Israel escalated its response to the rocket attacks from Gaza, until the
ceasefire began in the evening of 26 August (50 days) a total of 5,779 trucks entered Gaza
with approximately 85,000 tons of food *, 997 tons of medical supplies, 20.37 million liters
of various types of fuel (diesel, benzene etc.), 4,843 tons of gas for domestic use and a
few thousand tons of other products. The fighting in general, and the deliberate targeting
of the crossings by Hamas, reduced the flow of goods because many drivers feared to
show up (on any given day only a quarter to a half of the trucks planned for actually came).
