Israel changes story over aid workers' deaths

The Israeli military has changed its story over the deaths of 15 Palestinian emergency and aid workers gunned down by IDF soldiers and buried in a mass grave in southern Gaza last month. Mobile phone footage taken from one of the victims shows two marked ambulances were stopped by soldiers before gunfire broke out, contradicting Israeli claims that the vehicles had their lights off and were advancing suspiciously.
