As the occupying power, Israel has a duty under international law to ensure the welfare of Gaza’s inhabitants, including their rights to health, education, food and adequate housing
--------------------------------
In Gaza, Israeli attacks damaged or destroyed civilian buildings and infrastructure, including hospitals and schools, the water and electricity systems. Thousands of Palestinian homes were destroyed or severely damaged.
An estimated 280 of the 641 schools in Gaza were damaged and 18 were destroyed. More than half of Gaza’s population is under the age of 18 and the disruption to their education, due to the damage caused during Operation “Cast Lead” and as a result of the continuing Israeli boycott, is having a devastating impact.
Hospitals have also been badly affected by the military offensive and the blockade. Trucks of medical aid provided by the World Health Organization have been repeatedly refused entry to Gaza without explanation by Israeli officials.
Patients with serious medical conditions that cannot be treated in Gaza continue to be prevented or delayed from leaving Gaza by the Israeli authorities – since the closure of crossings leading into and out of Gaza, patients have been made to apply for permits, but these permits are frequently denied. On 1 November 2009, Samir al-Nadim, a father of three children, died after his exit from Gaza for a heart operation was delayed by 22 days.
Amnesty International spoke to a number of families whose homes were destroyed in the Israeli military operation and one year on are still living in temporary accommodation.
