“The majority of these [Palestinian] children were killed and injured while going about normal daily activities, such as going to school, playing, shopping, or simply being in their homes. Sixty-four percent of children killed during the first six months of 2003 died as a result of Israeli air and ground attacks, or from indiscriminate fire from Israeli soldiers.”
Source: Remember These Children, a coalition of groups calling for an end to the killing of children and a fair resolution of the conflict. (View the complete list of the victims, which was last updated on July 21, 2014. The list does not yet mention all of the 500 children killed by Israel in the current assault on Gaza.) Note: A child is a person aged 17 or younger.
It also appears that Remember These Children has not yet documented a number of the Palestinian children killed during Israel's Dec 27, 2008 - Jan 18, 2009 assault on Gaza. They report only 269 of the Palestinian children killed during that time (and an additional 9 who later died from wounds inflicted during that time period). B'Tselem has documented that Israel killed 318 Palestinian children in Gaza during this time. We do not doubt the validity of this higher number as they are extremely careful in their documentation.
