Israel pressed on with its bombing of Gaza on Tuesday after saying its campaign to destroy Hamas has left the Palestinian militant group on the "the verge of dissolution". Humanitarian leaders fear the besieged territory will soon be overwhelmed by disease and starvation, and are piling diplomatic pressure on Israel to boost efforts to protect civilians, AFP said. Fighting raged on Tuesday, with Hamas saying clashes had taken place in central Gaza and witnesses reporting deadly Israeli strikes in the south of the territory.
