From Amnesty International USA:
Since December 27, these horrific attacks on Gaza have caused over 400 Palestinian deaths and 2000 injuries. Rocket fire by armed Palestinian groups, including Hamas, has taken the lives of 4 Israelis and caused several dozen injuries. Amnesty International condemns the violence on both sides and calls on both parties to abide by international law and policies.
The U.S. government cannot continue this lop-sided blame on Hamas for the crisis. Ask Secretary Rice to urgently express deep concern about Israel's disproportional response and its policies which have brought the Gaza Strip to the brink of humanitarian disaster.
Civilians in Gaza, already trapped in disgraceful humanitarian conditions, are victims of Israeli air strikes and intensified attacks. Israeli blockades of humanitarian supplies continue to deny Palestinians the food and medical supplies they desperately need.
