More than 75,000 Palestinians were killed in the first 15 months of Israel¡¯s military assault in Gaza, a figure far higher than the 49,000 deaths local health officials announced at the time, says a new study by The Lancet Global Health medical journal.

The peer-reviewed study, published on Wednesday, found that women, children and ?the elderly comprised some 56.2% of violent deaths in Gaza during that period, a composition that it said roughly aligned ?with reporting ?by Gaza¡¯s health ministry.

The field work was conducted by the Palestinian Center for Policy and ?Survey Research, run by Palestinian pollster Khalil Shikaki, who has carried out public opinion polling in the West Bank and Gaza for decades. The lead author is Michael Spagat, a professor at Royal Holloway, University of London.
