Aid organisations say medical supplies and food are urgently needed in Gaza. Even before the airstrikes, a blockade on the territory by the Israeli government since June has been causing extreme hardship. Under-resourced hospitals say they simply cannot cope with the influx of victims and there is a severe shortage of medicine and equipment.UN workers say at least 50 civilians are among those killed, and hundreds more including women and children have been injured. One report also says nine UN workers are among those who died. As the UN and Western governments continue to call for an immediate ceasefire, the Israeli government has agreed to let in a further 120 trucks carrying aid. Despite the large number of civilian casualties, the Israeli government maintains ordinary citizens are not the targets. But it says it will let in as much aid as is needed.
