Israel blames Hamas for primitive homemade rocket attacks on the nearby Israeli city of Sederot. In 2001-2008, these rockets killed about 15 Israelis and injured 433, and they have damaged property. In the same period, Gazan mortar attacks on Israel have killed 8 Israelis. Since the Second Intifada broke out in 2000, Israelis have killed nearly 5000 Palestinians, nearly a thousand of them minors. Since fall of 2007, Israel has kept the 1.5 million Gazans under a blockade, interdicting food, fuel and medical supplies to one degree or another. Wreaking collective punishment on civilian populations such as hospital patients denied needed electricity is a crime of war.
