UN says Israeli strikes on Gaza killing over 100 are 'appalling'

The United Nations has called Israeli strikes on Gaza overnight "appalling" and urged all sides not to let peace "slip from our grasp".

"Reports that over 100 Palestinians were killed overnight in a wave of Israeli air strikes mainly on residential buildings, IDP tents and schools across the Gaza Strip, following the death of an Israeli soldier, are appalling," UN rights chief Volker Turk said in a statement.
